The author of this application requires me to send special characters
like
0xF0, 0xF1, .. to my device. Preferably, I would like to be able to do
this
inside GNU screen.
I suppose you could use a combination of 'stuff' and 'bindkey' to
redefine some of your keys to send these sequences:
You can stuff characters by octal ASCII value, e.g. ":stuff \041" would
stuff character '!' (convert 041 to decimal: 0 * 64 + 4 * 8 + 1 = 33 ).
0xF0 would be '360' in octal so you could consider
:bindkey -k F1 stuff \360
This would stuff in 0xf0 each time you pressed F11. See man screen under
bindkey and stuff for more information on these two friends. Handy
keys/sequences to 'reprogram' this way are the function keys, some
ctrl-<key> combinations (ones you don't use for anything else, so
probably NOT ctrl-a or ctrl-c, but perhaps ctrl-\ or ctrl-_) or
<esc>-<key> combinations (as you can usually easily enter these by
pressing alt-<key>, or otherwise hitting <esc> and the <key> in quick
succession is also easy enough to do)
Hope this helps,
Pieter.
