I need to implement a tiny protocol that requires answers after each
polling sequence. I planned to do it in user-mode, but it seems that there
is a very large indeed delay to the received data become available from
tty driver in the kernel.
May someone give me a line discipline or another serial driver without
task switches or really faster (at most 1ms, instead of the 20ms delay)?
I prefer to do my protocol in user code, because it will be more universal
to the users, but I can think of programming a device driver if I need to.
best regards,
Rildo Pragana
