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.
Changed so that the "ctrl-t ctrl-t" sequence is now simply "ctrl-t t" to
send the ctrl-t key code. This is inspired by screen which does similar
to send its command key code (ctrl-a a).
This change also allows to easier add new key commands if needed.
Updated man page accordingly.
After renaming to "tio" it makes sense to change the escape key
accordingly. Hence, the new escape key is ^t.
Meaning, in session, its now ctrl-t + q to quit.
Renamed to "tio" because it is shorter and this new name also more
precisely reflects what the program is - a simple TTY terminal I/O
application.
"tio" can be considered short for terminal I/O or TTY I/O or a
combination of the two, whichever you prefer.
Also, wanted to avoid naming conflicts with other projects.
