The program can be started in line editing mode. In this mode, the
current line can be edited by inserting/deleting characters. Escape
values can be used for bytes.
Controls:
printable - adds character to the position of the cursor
RIGHT, LEFT - moves cursor in the line
UP, DOWN - gets prevoiusly sent lines from the history
BACKSPACE - deletes character before the cursor
ENTER - sends line
Commands:
:? - list available commands
:q - quit
:v - show version
:: - send ':'
Escapes:
\dNNN - decimal NNN (e.g: \d045 = 45)
\xNN - hexadecimal NN (e.g: \xff = 255)
\bNNNNNNNN - binary NNNNNNNN (e.g: \b00000001 = 1)
Added option --line-edit, to start the program in line editing mode.
Added option --no-newline-in-line-edit to prevent sending newline
characters.
While in hex mode (ctrl-t h) you can output hexadecimal values.
E.g.: to send 0x0A you have to type 0A (always 2 characters).
Added option -x, --hex to start in hexadecimal mode.
Added option --newline-in-hex to interpret newline characters in hex mode.
This is disabled by default, because, in my opinion, hex stream is
fundamentally different from text, so a "new line" is meaningless in this
context.
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.
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.
