- Update to version 3.1
* Added the --raise-dtr and --raise-rts options, for symmetry with
- -lower-dtr and --lower-rts (see manual page for details)
* Better build support for custom baudrates. Now custom baudrate
support is enabled by default for some systems
* You can always explicitly enable custom baudrate support for
other systems and you can explicitly disable it, even for the
systems it is automatically enabled for (see Makefile).
* To see if custom baudrate support is enabled in your build, run
picocom with the --help command-line option.
- Includes 3.0
* Added the --logfile command line option
* Added the --lower-rts and --lower-dtr command-line options.
These options lower (reset) the respective modem control lines
of the serial port, as soon as picocom starts and the port
* Added the --initstring (or -t) command line option. This option
can be used to send an initialization string to the serial port
when picocom starts.
* Added the --exit-after (or -x) command line option. Causes
picocom to exit if it becomes idle for the specified time.
* Added the -exit (or -X) command line option. Causes picocom to
exit immediately after opening and configuring the serial port.
* Added the --quiet (or -q) command line option. Suppress output
from picocom that was not explicitly requested by the user.
Errors and command responses are still printed.
* Added the --no-escape (or -n) command line option. Disables the
escape character. If given picocom will never enter command mode.
* Added the --hangup (or -u) comand line option. If given
together with --noreset, picocom will not reset the serial port
to it's original settings on exit, but it will clear the modem
control lines (typically DTR and RTS) to signal a modem hangup.
* Added the [C-g] command that toggles the state of the RTS modem
. control line.
* Added the [C-w] command (write hex) that pompts the user for a
string of hexadecimal values to be converted to binary and sent
to the port.
* Added "to hex" character mappings (???hex), which replace
characters with their hexadecimal representation. For more see
issue #75, and the INPUT, OUTPUT, AND ECHO MAPPING section in
the picocom manual.
* Standard input can now be a non-tty (e.g a file or a pipe).
Useful in some occasions for doing trivial non-interactive stuff.
* Changed the way picocom handles reading zero-bytes from the
standard input. Now picocom waits for the output queue to be
transmitted before exiting, or waits to become idle before
exiting (if the --exit-after option is given). See the new
section EXITING PICOCOM in the manual for details.
* Picocom's serial port output queue is now dynamically growable.
You can still set an upper limit when compiling picocom, or
allow it to grow as much as your system's memory allows.
Usueful, for example, for doing huge copy-pastes.
* Fixed some minor backwards compatibility issues. Now you can use
command-line options compatible with 1.x.
* Now SIGINT, as well as SIGTERM, can kill picocom. May be useful
when the standard input is not a tty.
- Includes 2.2
* Improvement to read-buffering which can noticeably reduce CPU
load under high baudrates.
- Includes 2.0
* The "change-databits" command-key has been reasigned (from C-b
to C-i); to make room for the new command "set baudrate" (C-b,
see below), and for some symmetry with the new "set stopbits"
* The short option letter for the --parity command line option has
been changed from -p to -y; to leave -p for the new --stopbits
command-line option (see below).
* The default name for the history file has been changed to:
'.picocom_history' (in the user's home dir).
* The default input buffer size TTY_Q_SZ has been increased to
32KB. You can change it by editing the Makefile if you wish.
* You can now select between 1 or 2 stopbits for the serial port,
either via command-line option (--stopbits) or via command (C-j).
* Added new command (C-b) that allows you to enter a baudrate
numerically. This is particularly useful if you have compiled-in
the "custom baudrates" feature (see below), as it allows you to
enter arbitrary baudrate values. The old baud-up (C-u) and baud-down
(C-d) commands are still available.
* Added command that prints a list of all available command-keys
(C-h or C-k).
* It is now possible to disable the send- and receive-file commands
(C-s, and C-r) by supplying an empty string as the argument to
the --send-cmd and --receive-cmd options, respectively. When
both commands are disabled, picocom no longer forks or executes
any external programs.
* Picocom no longer uses /bin/sh to run external commands for
file-transfer operations. Parsing the command line and spliting
it into arguments is now performed internally by picocom, using
quoting rules very similar to those of the Unix shell. Hopefully,
this makes it impossible to inject shell-commands when supplying
filenames and extra arguments to the send- and receive-file
* Much improved serial-port settings handling and reporting.
Whenever a port-setting is changed (baud-rate, parity,
flow-control, etc) by a command, the serial port attributes are
re-read, and if found different from the requested value, both
values are displayed (first the requested, then the actual in
parenthesis). The show-status command (C-v) also re-reads the
actual terminal attributes and displays both: the requested
values and the actual terminal settings (if they differ). This
way C-v is able to "see" changes made to the serial-port outside
of picocom (or changes made from within picocom but silently
ignored by the serial port driver---which happens).
* The show-status command (C-v) also displays the current status
of the modem control lines (DTR, DSR, DCD, RTS, CTS, and RI)
* Picocom is now more clever regarding its output (writting to the
serial port) pacing. It no longer calls write(2) to send (overly)
large chucks to the tty in a single gulp. It limits the amount
of data write(2) can send to the tty on a single call, based on
the port's baud rate. This way no huge output buffers (relative
to the baud-rate) accumulate, and they don't take "forever" to
* Added support for setting custom (arbitrary) serial-port baud
rates. With this compiled-in you can, for example, set the
serial-port's baudrate to 42000 bps, or 1234 bps, or other such
arbitrary values. Custom baudrates can be set either through
the command-line option (--baud), or using the new command "set
baudrate* (C-b). By default the USE_CUSTOM_BAUD feature is NOT
compiled in. You have to comment-in the respective lines in the
Makefile and recompile picocom to enable it.
* Added compile-time option (NO_HELP) that allows you to compile
picocom without including any help strings. Disabled by default.

- Update to version 1.8
* Adds support for the "linenoise" library, which allows line-editing
and path completion when entering filenames for receive- and
send-file operations. Support can be compiled-out if you wish.
* Allows you to cancel a file-transfer operation, while entering a
file name, by pressing C-c. This works with linenoise support and without.
* Adds support for more high baud-rates.
Now every baudrate above 115200 is compiled-in only if the respective
macros are defined in the system header files. This should allow
picocom with HIGH_BAUD support to compile cleanly for more systems.
* Input-buffer size (TTY_Q_SZ) now defined in Makefile, and defaults to 1024.
* Adds support for locking using flock(2) (now default). Old-style
UUCP-lockdir code is maintained. Preferred locking style is selected
via the Makefile.
* Debian's xmltoman is now used to format the manpage.
* Other minor fixes.
