Hello,
I looked at the documentation and came accros the fl_add_io_callback()
function. However I don't quite know how to use it. So I would
appreciate it if you send me your code. But I think I will get another
problem, since you look at the termination character. The data stream
sent is a binary data flow and has no termination character, so that
makes it impossible to look for a specific character.
Thanks
Alain
