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.
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> "
Also changes default timestamp format from ISO8601 to classic 24-hour
format as this is assumed to be the format that most users would prefer.
And reintroduces strict but optional ISO8601 format.
This feature allows to easily add more timestamp formats in the future.
Allow user to select which ANSI color code to use to colorize the tio
text. To successfully set the color the color code must be in the range
0..255.
If color code is negative tio will print all available ANSI colors.
The default color is changed to bold white to make tio defaults usable
for most users, including color blind users.
The following new mapping flags are added:
INLCRNL: Map NL to CR-NL on input.
ODELBS: Map DEL to BS on output.
Flags requested and tested by Jan Ciger (janoc).
Add a --map option which allows to map special characters, in particular CR and
NL characters which are used in various combinations on varios platforms.
A new key command 'ctrl-t h' is introduced which toggles between
hexidecial mode and normal mode. When in hexidecimal mode data received
will be printed in hexidecimal.
Rearranged the key commands:
ctrl-c (clear screen) is now
ctrl-l which is similar to the well known shell ctrl-l
ctrl-i (show settings information) is now
ctrl-c (show configuration)
Updated man page accordingly.
A new key command "ctrl-t i" is added to allow the user to display the
various session settings information (baudrate, databits, log file, etc.).
This is usefull in case you have a running session but have forgotten
what the settings are.
To display the total number of bytes transmitted/received simply perform the
'ctrl-t s' command sequence.
This feature can be useful when eg. trying to detect non-printable
characters.
