=== tio v1.38 ===
Changes since tio v1.37:
* Redirect error messages to stderr
* Improve help and man page
* Mention config file in --help
* Fix running without config file
* Fix config file error messages
* Redirect error messages to stderr
* Add repology packaging status
* Fix parsing of default settings
Default configuration file settings were not parsed in case a section
was matched. Now we make sure that the default (unnamed) settings are
always parsed.
* Append to existing log file (no truncation)
* Add socket info to show configuration
* Print socket info at startup
* Fix socket option parsing
Peter Collingbourne:
* Match user input against config section names if pattern matching was unsuccessful.
This allows for better config file ergonomics if the user has a diverse
set of serial devices as the name does not need to be specified in
the config file twice.
* Add support for external control via a Unix domain socket.
This feature allows an external program to inject output into and
listen to input from a serial port via a Unix domain socket (path
specified via the -S/--socket command line flag, or the socket
config file option) while tio is running. This is useful for ad-hoc
scripting of serial port interactions while still permitting manual
control. Since many serial devices (at least on Linux) get confused
when opened by multiple processes, and most commands do not know
how to correctly open a serial device, this allows a more convenient
usage model than directly writing to the device node from an external
program.
Any input from clients connected to the socket is sent on the serial
port as if entered at the terminal where tio is running (except that
ctrl-t sequences are not recognized), and any input from the serial
port is multiplexed to the terminal and all connected clients.
Sockets remain open while the serial port is disconnected, and writes
will block.
Example usage 1 (issue a command):
echo command | nc -UN /path/to/socket > /dev/null
Example usage 2 (use the expect command to script an interaction):
#!/usr/bin/expect -f
set timeout -1
log_user 0
spawn nc -UN /path/to/socket
set uart $spawn_id
send -i $uart "command1\n"
expect -i $uart "prompt> "
send -i $uart "command2\n"
expect -i $uart "prompt> "

* fix for using option 'log' without 'log-filename' in config file
