1834+by Nick Patavalis (npat@efault.net)
1835+
1836+As its name suggests, [picocom] is a minimal dumb-terminal emulation
1837+program. It is, in principle, very much like minicom, only it's "pico"
1838+instead of "mini"! It was designed to serve as a simple, manual, modem
1839+configuration, testing, and debugging tool. It has also served (quite
1840+well) as a low-tech "terminal-window" to allow operator intervention
1841+in PPP connection scripts (something like the ms-windows "open
1842+terminal window before / after dialing" feature). It could also prove
1843+useful in many other similar tasks. It is ideal for embedded systems
1844+since its memory footprint is minimal (less than 20K, when
1845+stripped). Apart from being a handy little tool, [picocom] source
1846+distribution includes a simple, easy to use, and thoroughly documented
1847+terminal-management library, which could serve other projects as
1848+well. This library hides the termios(3) calls, and provides a less
1849+complex and safer (though certainly less feature-rich)
1850+interface. [picocom] runs on Linux, and with minor modifications it
1851+could run on any Unix system with the termios(3) library.
1852+
1853+For a description of picocom's operation, its command line options,
1854+and usage examples, see the manual page included in the source
1855+distribution as "picocom.8", and also html-ized as "picocom.8.html".
1856+
1857+People who have contibuted to picocom, by offering feature
1858+implementations, bug-fixes, corrections, and suggestions are listed in
1859+the "CONTRIBUTORS" file.
1860+
1861+The latest version of "picocom" can be downloaded from:

1876+ *
1877+ * Simple terminal management library. Wraps termios(3), and
1878+ * simplifies the logistics required for the reliable management and
1879+ * control of terminals.
1880+ *
1881+ * Principles of operation:
1882+ *
1883+ * After the library is initialized one or more file-descriptors, can
1884+ * be added to (and latter removed from) the list managed by the
1885+ * library (framework). These file descriptos must be opened on
1886+ * terminal devices. For every fd, the original settings of the
1887+ * associated terminal device are saved by the library. These settings
1888+ * are restored when the fd is removed from the framework, or at
1889+ * porgram termination [by means of an atexit(3) handler installed by
1890+ * the library], or at user request. The library maintains three
1891+ * structures for every fd in the framework: The original settings
1892+ * structure ("origtermios"), keeping the setings of the terminal
1893+ * device when the respective filedes was added to the framework. The
1894+ * current settings structure ("currtermios"), keeping the current
1895+ * setings of the associated terminal device; and the next settings
1896+ * structure ("nexttermios") which keeps settings to be applied to the
1897+ * associated terminal device at a latter time, upon user request.
1898+ * The "term_set_*" functions can be used to modify the device
1899+ * settings stored in the nexttermios structure. Using functions
1900+ * provided by the library the user can: Apply the nexttermios
1901+ * settings to the device. Revert all changes made on nexttermios by
1902+ * copying the currtermios structure to nexttermios. Reset the device,
1903+ * by configuring it to the original settings, and copying origtermios
1904+ * to currtermios and nexttermios. Refresh the device by rereading the
1905+ * current settings from it and updating currtermios (to catch up with
1906+ * changes made to the device by means outside of this framework).
1907+ *
1908+ * Interface summary:
1909+ *

2435+ <description>
2436+
2437+ <p>
2438+ As its name suggests, <cmd>picocom</cmd> is a minimal
2439+ dumb-terminal emulation program. It is, in principle, very much
2440+ like <manref name="minicom" section="1"/>, only it's "pico"
2441+ instead of "mini"! It was designed to serve as a simple, manual,
2442+ modem configuration, testing, and debugging tool. It has also
2443+ served (quite well) as a low-tech "terminal-window" to allow
2444+ operator intervention in PPP connection scripts (something like
2445+ the ms-windows "open terminal window before / after dialing"
2446+ feature). It could also prove useful in many other similar
2447+ tasks.
2448+ </p>
2449+
2450+ <p>
2451+ When <cmd>picocom</cmd> starts it opens the terminal (serial
2452+ device) given as its non-option argument. Unless the
2453+ <arg>--noinit</arg> option is given, it configures the device to
2454+ the settings specified by the option-arguments (or to some
2455+ default settings), and sets it to "raw" mode. If
2456+ <arg>--noinit</arg> is given, the initialization and
2457+ configuration is skipped; the device is just opened. Following
2458+ this, <cmd>picocom</cmd> sets the standard-input and
2459+ standard-output to raw mode. Having done so, it goes in a loop
2460+ where it listens for input from stdin, or from the serial
2461+ port. Input from the serial port is copied to the standard
2462+ output while input from the standard input is copied to the
2463+ serial port. <cmd>picocom</cmd> also scans its input stream for
2464+ a user-specified control character, called the "escape
2465+ character" (being by default "C-a"). If the escape character is
2466+ seen, then instead of sending it to the serial-device, the
2467+ program enters "command mode" and waits for the next character
2468+ (which is called the "function character"). Depending on the
2469+ value of the function character, <cmd>picocom</cmd> performs one
2470+ of the operations described in the "Commands" section below.
2471+ </p>
2472+ </description>
2473+
2474+ <section name="COMMANDS">
2475+
2476+ <p>
2477+ Commands are given to <cmd>picocom</cmd> by first keying the
2478+ "espace character" which by default is "C-a" (see "Options"
2479+ below on how to change it), and then keying one for the function
2480+ (command) characters shown here.

2485+ <dd>
2486+ <p>
2487+ Send the escape character to the serial port and return to
2488+ "transparent" mode. This means that if the escape character
2489+ ("C-a", by default) is typed twice, the program sends the
2490+ escape character to the serial port, and remains in
2491+ transparent mode. This is a new behavior implemented in
2492+ v1.4. Previously picocom used to ignore the escape-character
2493+ when it was entered as a function character.

2621+ <p>
2622+ <cmd>picocom</cmd> can send and receive files over the serial
2623+ port using external programs that implement the respective
2624+ protocols. In Linux typical programs for this purpose are:
2625+ </p>
2626+
2627+ <ul>
2628+ <li><p><manref name="rx" section="1"/>
2629+ - receive using the X-MODEM protocol</p></li>
2630+ <li><p><manref name="rb" section="1"/>
2631+ - receive using the Y-MODEM protocol</p></li>
2632+ <li><p><manref name="rz" section="1"/>
2633+ - receive using the Z-MODEM protocol</p></li>
2634+ <li><p><manref name="sx" section="1"/>
2635+ - send using the X-MODEM protocol</p></li>
2636+ <li><p><manref name="sb" section="1"/>
2637+ - send using the Y-MODEM protocol</p></li>
2638+ <li><p><manref name="sz" section="1"/>
2639+ - send using the Z-MODEM protocol</p></li>
2640+ <li><p><manref name="ascii-xfr" section="1"/>
2641+ - receive or transmit ASCII files</p></li>
2642+ </ul>
2643+
2644+ <p>
2645+ The name of, and the command-line options to, the program to be
2646+ used for transmitting files are given by the "--send-cmd"
2647+ option. Similarly the program to receive files, and its
2648+ argumets, are given by the "--receive-cmd" option. For example,
2649+ in order to start a <cmd>picocom</cmd> session that uses "sz" to
2650+ transmit files, and "rz" to receive, you have to say something
2651+ like this:
2652+ </p>
2653+
2654+ <p>
2655+ picocom --send-cmd "sz -vv" --receive-cmd "rz -vv"
2656+ </p>
2657+
2658+ <p>
2659+ During the picocom session, if you key the "send" or "receive"
2660+ commands (e.g. by pressing C-a, C-s, or C-a, C-r) you will be
2661+ prompted for a filename. At this prompt you can enter one or
2662+ more file-names, and any additional arguments to the
2663+ transmission or reception program. After that, picocom will
2664+ start the the external program as specified by the "--send-cmd",
2665+ or "--receive-cmd" option, and with any filenames and additional
2666+ arguments you may have supplied. The standard input and output
2667+ of the external program will be connected to the serial
2668+ port. The standard error of the external program will be
2669+ connected to the terminal which---while the program is
2670+ running---will revert to canonical mode. Pressing 'C-c' while
2671+ the external program is running will prematurely terminate it,
2672+ and return control to <cmd>picocom</cmd>. Pressing 'C-c' at any other
2673+ time, has no special effect; the character is normally passed to
2674+ the serial port.

2831+.SH NAME
2832+picocom \- minimal dumb-terminal emulation program
2833+.SH SYNOPSIS
2834+.B picocom [
2835+.I options
2836+.B ]
2837+.I device
2838+.br
2839+.SH DESCRIPTION
2840+As its name suggests,
2841+.B picocom
2842+is a minimal dumb-terminal emulation program. It is, in principle, very much like
2843+.B minicom(1)
2844+, only it's "pico" instead of "mini"! It was designed to serve as a simple, manual, modem configuration, testing, and debugging tool. It has also served (quite well) as a low-tech "terminal-window" to allow operator intervention in PPP connection scripts (something like the ms-windows "open terminal window before / after dialing" feature). It could also prove useful in many other similar tasks.
2845+.br
2846+.sp 0.6v
2847+When
2848+.B picocom
2849+starts it opens the terminal (serial device) given as its non-option argument. Unless the
2850+.I --noinit
2851+option is given, it configures the device to the settings specified by the option-arguments (or to some default settings), and sets it to "raw" mode. If
2852+.I --noinit
2853+is given, the initialization and configuration is skipped; the device is just opened. Following this,
2854+.B picocom
2855+sets the standard-input and standard-output to raw mode. Having done so, it goes in a loop where it listens for input from stdin, or from the serial port. Input from the serial port is copied to the standard output while input from the standard input is copied to the serial port.
2856+.B picocom
2857+also scans its input stream for a user-specified control character, called the "escape character" (being by default "C-a"). If the escape character is seen, then instead of sending it to the serial-device, the program enters "command mode" and waits for the next character (which is called the "function character"). Depending on the value of the function character,
2858+.B picocom
2859+performs one of the operations described in the "Commands" section below.
2860+.br
2861+.sp 0.6v
2862+.SH COMMANDS
2863+Commands are given to
2864+.B picocom
2865+by first keying the "espace character" which by default is "C-a" (see "Options" below on how to change it), and then keying one for the function (command) characters shown here.
2866+.TP 3
2867+.B [escape character]
2868+Send the escape character to the serial port and return to "transparent" mode. This means that if the escape character ("C-a", by default) is typed twice, the program sends the escape character to the serial port, and remains in transparent mode. This is a new behavior implemented in v1.4. Previously picocom used to ignore the escape-character when it was entered as a function character.
2869+.TP 3
2870+.B C-x
2871+Exit the program: if the "--noreset" option was not given then the serial port is reset to its original settings before exiting; if it was given the serial port is not reset.
2872+.TP 3
2873+.B C-q
2874+Quit the program *without* reseting the serial port, regardless of the "--noreset" option.
2875+.TP 3
2876+.B C-p
2877+Pulse the DTR line. Lower it for 1 sec, and then raise it again.
2878+.TP 3
2879+.B C-t
2880+Toggle the DTR line. If DTR is up, then lower it. If it is down, then raise it.
2881+.TP 3
2882+.B C-\e
2883+Generate a break sequence on the serial line. A break sequence is usually generated by marking (driving to logical one) the serial Tx line for an amount of time coresponding to several character durations.
2884+.TP 3
2885+.B C-u
2886+Baud up. Increase the baud-rate. The list of baud-rates stepped-through by this command is: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200.
2887+.TP 3
2888+.B C-d
2889+Baud down. Decrease the baud-rate. The list of baud-rates stepped-through by this command is the same as for the "baud-up" command.
2890+.TP 3
2891+.B C-f
2892+Cycle through flow-control settings (RTS/CTS, XON/XOFF, none).
2893+.TP 3
2894+.B C-y
2895+Cycle through parity settings (even, odd, none).
2896+.TP 3
2897+.B C-b
2898+Cycle through databits-number settings (5, 6, 7, 8).
2899+.TP 3
2900+.B C-v
2901+Show program options (like baud rate, data bits, etc). Only the options that can be modified online (through commands) are shown, not those that can only be set at the command-line.
2902+.TP 3
2903+.B C-s
2904+Send (upload) a file (see "Sending and Receiving Files" below)
2905+.TP 3
2906+.B C-r
2907+Receive (download) a file (see "Sending and Receiving Files" below)
2908+.PP
2909+After performing one of the above operations the program leaves the command mode and enters transparent mode. Example: To increase the baud-rate by two steps, you have to type:
2910+.br
2911+.sp 0.6v
2912+C-a, C-u, C-a, C-u
2913+.br
2914+.sp 0.6v
2915+assuming of-course that "C-a" is the escape character.
2916+.br
2917+.sp 0.6v
2918+.SH SENDING AND RECEIVING FILES
2919+.B picocom
2920+can send and receive files over the serial port using external programs that implement the respective protocols. In Linux typical programs for this purpose are:
2921+.IP \(em 3
2922+.B rx(1)
2923+- receive using the X-MODEM protocol
2924+.IP \(em 3
2925+.B rb(1)
2926+- receive using the Y-MODEM protocol
2927+.IP \(em 3
2928+.B rz(1)
2929+- receive using the Z-MODEM protocol
2930+.IP \(em 3
2931+.B sx(1)
2932+- send using the X-MODEM protocol
2933+.IP \(em 3
2934+.B sb(1)
2935+- send using the Y-MODEM protocol
2936+.IP \(em 3
2937+.B sz(1)
2938+- send using the Z-MODEM protocol
2939+.IP \(em 3
2940+.B ascii-xfr(1)
2941+- receive or transmit ASCII files
2942+.PP
2943+The name of, and the command-line options to, the program to be used for transmitting files are given by the "--send-cmd" option. Similarly the program to receive files, and its argumets, are given by the "--receive-cmd" option. For example, in order to start a
2944+.B picocom
2945+session that uses "sz" to transmit files, and "rz" to receive, you have to say something like this:
2946+.br
2947+.sp 0.6v
2948+picocom --send-cmd "sz -vv" --receive-cmd "rz -vv"
2949+.br
2950+.sp 0.6v
2951+During the picocom session, if you key the "send" or "receive" commands (e.g. by pressing C-a, C-s, or C-a, C-r) you will be prompted for a filename. At this prompt you can enter one or more file-names, and any additional arguments to the transmission or reception program. After that, picocom will start the the external program as specified by the "--send-cmd", or "--receive-cmd" option, and with any filenames and additional arguments you may have supplied. The standard input and output of the external program will be connected to the serial port. The standard error of the external program will be connected to the terminal which---while the program is running---will revert to canonical mode. Pressing 'C-c' while the external program is running will prematurely terminate it, and return control to
2952+.B picocom
2953+. Pressing 'C-c' at any other time, has no special effect; the character is normally passed to the serial port.

3054+ Everyone is permitted to copy and distribute verbatim copies
3055+ of this license document, but changing it is not allowed.
3056+
3057+ Preamble
3058+
3059+ The licenses for most software are designed to take away your
3060+freedom to share and change it. By contrast, the GNU General Public
3061+License is intended to guarantee your freedom to share and change free
3062+software--to make sure the software is free for all its users. This
3063+General Public License applies to most of the Free Software
3064+Foundation's software and to any other program whose authors commit to
3065+using it. (Some other Free Software Foundation software is covered by
3066+the GNU Library General Public License instead.) You can apply it to
3067+your programs, too.
3068+
3069+ When we speak of free software, we are referring to freedom, not
3070+price. Our General Public Licenses are designed to make sure that you
3071+have the freedom to distribute copies of free software (and charge for
3072+this service if you wish), that you receive source code or can get it
3073+if you want it, that you can change the software or use pieces of it
3074+in new free programs; and that you know you can do these things.
3075+
3076+ To protect your rights, we need to make restrictions that forbid
3077+anyone to deny you these rights or to ask you to surrender the rights.
3078+These restrictions translate to certain responsibilities for you if you
3079+distribute copies of the software, or if you modify it.
3080+
3081+ For example, if you distribute copies of such a program, whether
3082+gratis or for a fee, you must give the recipients all the rights that
3083+you have. You must make sure that they, too, receive or can get the
3084+source code. And you must show them these terms so they know their
3085+rights.
3086+
3087+ We protect your rights with two steps: (1) copyright the software, and
3088+(2) offer you this license which gives you legal permission to copy,
3089+distribute and/or modify the software.
3090+
3091+ Also, for each author's protection and ours, we want to make certain
3092+that everyone understands that there is no warranty for this free
3093+software. If the software is modified by someone else and passed on, we
3094+want its recipients to know that what they have is not the original, so
3095+that any problems introduced by others will not reflect on the original
3096+authors' reputations.
3097+
3098+ Finally, any free program is threatened constantly by software
3099+patents. We wish to avoid the danger that redistributors of a free
3100+program will individually obtain patent licenses, in effect making the
3101+program proprietary. To prevent this, we have made it clear that any
3102+patent must be licensed for everyone's free use or not licensed at all.

3110+ 0. This License applies to any program or other work which contains
3111+a notice placed by the copyright holder saying it may be distributed
3112+under the terms of this General Public License. The "Program", below,
3113+refers to any such program or work, and a "work based on the Program"
3114+means either the Program or any derivative work under copyright law:
3115+that is to say, a work containing the Program or a portion of it,
3116+either verbatim or with modifications and/or translated into another
3117+language. (Hereinafter, translation is included without limitation in
3118+the term "modification".) Each licensee is addressed as "you".
3119+
3120+Activities other than copying, distribution and modification are not
3121+covered by this License; they are outside its scope. The act of
3122+running the Program is not restricted, and the output from the Program
3123+is covered only if its contents constitute a work based on the
3124+Program (independent of having been made by running the Program).
3125+Whether that is true depends on what the Program does.
3126+
3127+ 1. You may copy and distribute verbatim copies of the Program's
3128+source code as you receive it, in any medium, provided that you
3129+conspicuously and appropriately publish on each copy an appropriate
3130+copyright notice and disclaimer of warranty; keep intact all the
3131+notices that refer to this License and to the absence of any warranty;
3132+and give any other recipients of the Program a copy of this License
3133+along with the Program.
3134+
3135+You may charge a fee for the physical act of transferring a copy, and
3136+you may at your option offer warranty protection in exchange for a fee.
3137+
3138+ 2. You may modify your copy or copies of the Program or any portion
3139+of it, thus forming a work based on the Program, and copy and
3140+distribute such modifications or work under the terms of Section 1
3141+above, provided that you also meet all of these conditions:
3142+
3143+ a) You must cause the modified files to carry prominent notices
3144+ stating that you changed the files and the date of any change.
3145+
3146+ b) You must cause any work that you distribute or publish, that in
3147+ whole or in part contains or is derived from the Program or any
3148+ part thereof, to be licensed as a whole at no charge to all third
3149+ parties under the terms of this License.
3150+
3151+ c) If the modified program normally reads commands interactively
3152+ when run, you must cause it, when started running for such
3153+ interactive use in the most ordinary way, to print or display an
3154+ announcement including an appropriate copyright notice and a
3155+ notice that there is no warranty (or else, saying that you provide
3156+ a warranty) and that users may redistribute the program under
3157+ these conditions, and telling the user how to view a copy of this
3158+ License. (Exception: if the Program itself is interactive but
3159+ does not normally print such an announcement, your work based on
3160+ the Program is not required to print an announcement.)
3161+\f
3162+These requirements apply to the modified work as a whole. If
3163+identifiable sections of that work are not derived from the Program,
3164+and can be reasonably considered independent and separate works in
3165+themselves, then this License, and its terms, do not apply to those
3166+sections when you distribute them as separate works. But when you
3167+distribute the same sections as part of a whole which is a work based
3168+on the Program, the distribution of the whole must be on the terms of
3169+this License, whose permissions for other licensees extend to the
3170+entire whole, and thus to each and every part regardless of who wrote it.
3171+
3172+Thus, it is not the intent of this section to claim rights or contest
3173+your rights to work written entirely by you; rather, the intent is to
3174+exercise the right to control the distribution of derivative or
3175+collective works based on the Program.
3176+
3177+In addition, mere aggregation of another work not based on the Program
3178+with the Program (or with a work based on the Program) on a volume of
3179+a storage or distribution medium does not bring the other work under
3180+the scope of this License.
3181+
3182+ 3. You may copy and distribute the Program (or a work based on it,
3183+under Section 2) in object code or executable form under the terms of
3184+Sections 1 and 2 above provided that you also do one of the following:
3185+
3186+ a) Accompany it with the complete corresponding machine-readable
3187+ source code, which must be distributed under the terms of Sections
3188+ 1 and 2 above on a medium customarily used for software interchange; or,
3189+
3190+ b) Accompany it with a written offer, valid for at least three
3191+ years, to give any third party, for a charge no more than your
3192+ cost of physically performing source distribution, a complete
3193+ machine-readable copy of the corresponding source code, to be
3194+ distributed under the terms of Sections 1 and 2 above on a medium
3195+ customarily used for software interchange; or,
3196+
3197+ c) Accompany it with the information you received as to the offer
3198+ to distribute corresponding source code. (This alternative is
3199+ allowed only for noncommercial distribution and only if you
3200+ received the program in object code or executable form with such
3201+ an offer, in accord with Subsection b above.)
3202+
3203+The source code for a work means the preferred form of the work for
3204+making modifications to it. For an executable work, complete source
3205+code means all the source code for all modules it contains, plus any
3206+associated interface definition files, plus the scripts used to
3207+control compilation and installation of the executable. However, as a
3208+special exception, the source code distributed need not include
3209+anything that is normally distributed (in either source or binary
3210+form) with the major components (compiler, kernel, and so on) of the
3211+operating system on which the executable runs, unless that component
3212+itself accompanies the executable.
3213+
3214+If distribution of executable or object code is made by offering
3215+access to copy from a designated place, then offering equivalent
3216+access to copy the source code from the same place counts as
3217+distribution of the source code, even though third parties are not
3218+compelled to copy the source along with the object code.
3219+\f
3220+ 4. You may not copy, modify, sublicense, or distribute the Program
3221+except as expressly provided under this License. Any attempt
3222+otherwise to copy, modify, sublicense or distribute the Program is
3223+void, and will automatically terminate your rights under this License.
3224+However, parties who have received copies, or rights, from you under
3225+this License will not have their licenses terminated so long as such
3226+parties remain in full compliance.
3227+
3228+ 5. You are not required to accept this License, since you have not
3229+signed it. However, nothing else grants you permission to modify or
3230+distribute the Program or its derivative works. These actions are
3231+prohibited by law if you do not accept this License. Therefore, by
3232+modifying or distributing the Program (or any work based on the
3233+Program), you indicate your acceptance of this License to do so, and
3234+all its terms and conditions for copying, distributing or modifying
3235+the Program or works based on it.
3236+
3237+ 6. Each time you redistribute the Program (or any work based on the
3238+Program), the recipient automatically receives a license from the
3239+original licensor to copy, distribute or modify the Program subject to
3240+these terms and conditions. You may not impose any further
3241+restrictions on the recipients' exercise of the rights granted herein.
3242+You are not responsible for enforcing compliance by third parties to
3243+this License.
3244+
3245+ 7. If, as a consequence of a court judgment or allegation of patent
3246+infringement or for any other reason (not limited to patent issues),
3247+conditions are imposed on you (whether by court order, agreement or
3248+otherwise) that contradict the conditions of this License, they do not
3249+excuse you from the conditions of this License. If you cannot
3250+distribute so as to satisfy simultaneously your obligations under this
3251+License and any other pertinent obligations, then as a consequence you
3252+may not distribute the Program at all. For example, if a patent
3253+license would not permit royalty-free redistribution of the Program by
3254+all those who receive copies directly or indirectly through you, then
3255+the only way you could satisfy both it and this License would be to
3256+refrain entirely from distribution of the Program.
3257+
3258+If any portion of this section is held invalid or unenforceable under
3259+any particular circumstance, the balance of the section is intended to
3260+apply and the section as a whole is intended to apply in other
3261+circumstances.
3262+
3263+It is not the purpose of this section to induce you to infringe any
3264+patents or other property right claims or to contest validity of any
3265+such claims; this section has the sole purpose of protecting the
3266+integrity of the free software distribution system, which is
3267+implemented by public license practices. Many people have made
3268+generous contributions to the wide range of software distributed
3269+through that system in reliance on consistent application of that
3270+system; it is up to the author/donor to decide if he or she is willing
3271+to distribute software through any other system and a licensee cannot
3272+impose that choice.
3273+
3274+This section is intended to make thoroughly clear what is believed to
3275+be a consequence of the rest of this License.
3276+\f
3277+ 8. If the distribution and/or use of the Program is restricted in
3278+certain countries either by patents or by copyrighted interfaces, the
3279+original copyright holder who places the Program under this License
3280+may add an explicit geographical distribution limitation excluding
3281+those countries, so that distribution is permitted only in or among
3282+countries not thus excluded. In such case, this License incorporates
3283+the limitation as if written in the body of this License.
3284+
3285+ 9. The Free Software Foundation may publish revised and/or new versions
3286+of the General Public License from time to time. Such new versions will
3287+be similar in spirit to the present version, but may differ in detail to
3288+address new problems or concerns.
3289+
3290+Each version is given a distinguishing version number. If the Program
3291+specifies a version number of this License which applies to it and "any
3292+later version", you have the option of following the terms and conditions
3293+either of that version or of any later version published by the Free
3294+Software Foundation. If the Program does not specify a version number of
3295+this License, you may choose any version ever published by the Free Software
3296+Foundation.
3297+
3298+ 10. If you wish to incorporate parts of the Program into other free
3299+programs whose distribution conditions are different, write to the author
3300+to ask for permission. For software which is copyrighted by the Free
3301+Software Foundation, write to the Free Software Foundation; we sometimes
3302+make exceptions for this. Our decision will be guided by the two goals
3303+of preserving the free status of all derivatives of our free software and
3304+of promoting the sharing and reuse of software generally.
3305+
3306+ NO WARRANTY
3307+
3308+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
3309+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
3310+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
3311+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
3312+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
3313+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
3314+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
3315+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
3316+REPAIR OR CORRECTION.
3317+
3318+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
3319+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
3320+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
3321+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
3322+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
3323+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
3324+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
3325+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
3326+POSSIBILITY OF SUCH DAMAGES.
3327+
3328+ END OF TERMS AND CONDITIONS
3329+\f
3330+ How to Apply These Terms to Your New Programs
3331+
3332+ If you develop a new program, and you want it to be of the greatest
3333+possible use to the public, the best way to achieve this is to make it
3334+free software which everyone can redistribute and change under these terms.
3335+
3336+ To do so, attach the following notices to the program. It is safest
3337+to attach them to the start of each source file to most effectively
3338+convey the exclusion of warranty; and each file should have at least
3339+the "copyright" line and a pointer to where the full notice is found.
3340+
3341+ <one line to give the program's name and a brief idea of what it does.>
3342+ Copyright (C) <year> <name of author>
3343+
3344+ This program is free software; you can redistribute it and/or modify
3345+ it under the terms of the GNU General Public License as published by
3346+ the Free Software Foundation; either version 2 of the License, or
3347+ (at your option) any later version.
3348+
3349+ This program is distributed in the hope that it will be useful,
3350+ but WITHOUT ANY WARRANTY; without even the implied warranty of
3351+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
3352+ GNU General Public License for more details.
3353+
3354+ You should have received a copy of the GNU General Public License
3355+ along with this program; if not, write to the Free Software
3356+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
3357+
3358+
3359+Also add information on how to contact you by electronic and paper mail.
3360+
3361+If the program is interactive, make it output a short notice like this
3362+when it starts in an interactive mode:
3363+
3364+ Gnomovision version 69, Copyright (C) year name of author
3365+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
3366+ This is free software, and you are welcome to redistribute it
3367+ under certain conditions; type `show c' for details.
3368+
3369+The hypothetical commands `show w' and `show c' should show the appropriate
3370+parts of the General Public License. Of course, the commands you use may
3371+be called something other than `show w' and `show c'; they could even be
3372+mouse-clicks or menu items--whatever suits your program.
3373+
3374+You should also get your employer (if you work as a programmer) or your
3375+school, if any, to sign a "copyright disclaimer" for the program, if
3376+necessary. Here is a sample; alter the names:
3377+
3378+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
3379+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

3383+
3384+This General Public License does not permit incorporating your program into
3385+proprietary programs. If your program is a subroutine library, you may
3386+consider it more useful to permit linking proprietary applications with the
3387+library. If this is what you want to do, use the GNU Library General
3388+Public License instead of this License.

3421+<h2>DESCRIPTION</h2>
3422+<center><table width="90%"><tr><td>
3423+ <p>
3424+ As its name suggests, <b>picocom</b> is a minimal dumb-terminal
3425+ emulation program. It is, in principle, very much like
3426+ <a href=""><b>minicom</b>(1)</a>, only it's "pico" instead of
3427+ "mini"! It was designed to serve as a simple, manual, modem
3428+ configuration, testing, and debugging tool. It has also served
3429+ (quite well) as a low-tech "terminal-window" to allow operator
3430+ intervention in PPP connection scripts (something like the
3431+ ms-windows "open terminal window before / after dialing" feature).
3432+ It could also prove useful in many other similar tasks.
3433+ </p>
3434+ <p>
3435+ When <b>picocom</b> starts it opens the terminal (serial device)
3436+ given as its non-option argument. Unless the <i>--noinit</i>
3437+ option is given, it configures the device to the settings
3438+ specified by the option-arguments (or to some default settings),
3439+ and sets it to "raw" mode. If <i>--noinit</i> is given, the
3440+ initialization and configuration is skipped; the device is just
3441+ opened. Following this, <b>picocom</b> sets the standard-input and
3442+ standard-output to raw mode. Having done so, it goes in a loop
3443+ where it listens for input from stdin, or from the serial port.
3444+ Input from the serial port is copied to the standard output while
3445+ input from the standard input is copied to the serial port. <b>picocom</b>
3446+ also scans its input stream for a user-specified control
3447+ character, called the "escape character" (being by default "C-a").
3448+ If the escape character is seen, then instead of sending it to the
3449+ serial-device, the program enters "command mode" and waits for the
3450+ next character (which is called the "function character").
3451+ Depending on the value of the function character, <b>picocom</b>
3452+ performs one of the operations described in the "Commands" section
3453+ below.
3454+ </p>
3455+</td></tr></table></center>
3456+
3457+<h2>COMMANDS</h2>
3458+<center><table width="90%"><tr><td>
3459+ <p>
3460+ Commands are given to <b>picocom</b> by first keying the "espace
3461+ character" which by default is "C-a" (see "Options" below on how
3462+ to change it), and then keying one for the function (command)
3463+ characters shown here.

3467+ [escape character]
3468+ </b></dt>
3469+ <dd>
3470+ <p>
3471+ Send the escape character to the serial port and return to
3472+ "transparent" mode. This means that if the escape character
3473+ ("C-a", by default) is typed twice, the program sends the
3474+ escape character to the serial port, and remains in
3475+ transparent mode. This is a new behavior implemented in v1.4.
3476+ Previously picocom used to ignore the escape-character when it
3477+ was entered as a function character.

3613+<h2>SENDING AND RECEIVING FILES</h2>
3614+<center><table width="90%"><tr><td>
3615+ <p>
3616+ <b>picocom</b> can send and receive files over the serial port
3617+ using external programs that implement the respective protocols.
3618+ In Linux typical programs for this purpose are:
3619+ </p>
3620+ <ul>
3621+ <li>
3622+ <p>
3623+ <a href=""><b>rx</b>(1)</a> - receive using the X-MODEM
3624+ protocol
3625+ </p>
3626+ </li>
3627+ <li>
3628+ <p>
3629+ <a href=""><b>rb</b>(1)</a> - receive using the Y-MODEM
3630+ protocol
3631+ </p>
3632+ </li>
3633+ <li>
3634+ <p>
3635+ <a href=""><b>rz</b>(1)</a> - receive using the Z-MODEM
3636+ protocol
3637+ </p>
3638+ </li>
3639+ <li>
3640+ <p>
3641+ <a href=""><b>sx</b>(1)</a> - send using the X-MODEM protocol
3642+ </p>
3643+ </li>
3644+ <li>
3645+ <p>
3646+ <a href=""><b>sb</b>(1)</a> - send using the Y-MODEM protocol
3647+ </p>
3648+ </li>
3649+ <li>
3650+ <p>
3651+ <a href=""><b>sz</b>(1)</a> - send using the Z-MODEM protocol
3652+ </p>
3653+ </li>
3654+ <li>
3655+ <p>
3656+ <a href=""><b>ascii-xfr</b>(1)</a> - receive or transmit ASCII
3657+ files
3658+ </p>
3659+ </li>
3660+ </ul>
3661+ <p>
3662+ The name of, and the command-line options to, the program to be
3663+ used for transmitting files are given by the "--send-cmd" option.
3664+ Similarly the program to receive files, and its argumets, are
3665+ given by the "--receive-cmd" option. For example, in order to
3666+ start a <b>picocom</b> session that uses "sz" to transmit files,
3667+ and "rz" to receive, you have to say something like this:
3668+ </p>
3669+ <p>
3670+ picocom --send-cmd "sz -vv" --receive-cmd "rz -vv"
3671+ </p>
3672+ <p>
3673+ During the picocom session, if you key the "send" or "receive"
3674+ commands (e.g. by pressing C-a, C-s, or C-a, C-r) you will be
3675+ prompted for a filename. At this prompt you can enter one or more
3676+ file-names, and any additional arguments to the transmission or
3677+ reception program. After that, picocom will start the the external
3678+ program as specified by the "--send-cmd", or "--receive-cmd"
3679+ option, and with any filenames and additional arguments you may
3680+ have supplied. The standard input and output of the external
3681+ program will be connected to the serial port. The standard error
3682+ of the external program will be connected to the terminal
3683+ which---while the program is running---will revert to canonical
3684+ mode. Pressing 'C-c' while the external program is running will
3685+ prematurely terminate it, and return control to <b>picocom</b>.
3686+ Pressing 'C-c' at any other time, has no special effect; the
3687+ character is normally passed to the serial port.

3793+ If given, <b>picocom</b> will not initialize, reset, or

3796+ to already-connected modems, or already configured ports

3809+ This is useful, for example, for leaving modems connected when

3811+ option is given the user can exit <b>picocom</b> using the
3812+ "Quit" command (instead of "Exit"), which never resets the

3825+ opening the port. Failing to do so, results in the program

3960+Added support for UUCP-style locks. Lock handling is compiled-in if

5117+version 1.1
5118+
5119+ - Added example shell-scripts that start picocom preconfigured for
5120+ ASCII, Z-MODEM, Y-MODEM, and X-MODEM file transfers.
5121+
5122+ - Better signal handling.
5123+
5124+ - Added the "send" and "receive" commands. They can be used to
5125+ transmit and receive files via external programs that implement
5126+ the respective protocols (like the programs "sz", "rz", etc).
5127+
5128+ - Added the "status" command, which shows the currently active
5129+ program options, like the current baud rate, the current
5130+ flow-control settings, etc. Only options that can be controlled
5131+ online are shown.
5132+
5133+ - Slight code restructuring.
5134+
5135+ - Minor bug fixes.
5136+
5137+version 1.0
