What about Peter's comments on this patch?
Peter's comments will import policy,
I means we should let userspace to decide whether
and when to restart tty with the mechanism of TCXONC
instead of restart tty accidental when make n_tty_set_termios
call.
There would be no accidental restart. Userspace is specifically
disabling user-controlled output flow control by clearing
IXON in termios. Userspace is _expecting_ a 'started' tty.
If you insist that this must be controllable from userspace,
then that is already possible:
tcflow(fd, TCOOFF);
tcflow(fd, TCOON);
