1.44 change was correct if user not set t_timeout directly
via special ioctl or comcontrol. By default t_timeout == 0 !!!
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This "fix" is _incorrect_, it obviously not fix this PR, becuase
t_timeout != 0 required for it. Moreover it cause modem hangs,
whan 1.44 code release it.
If user set t_timeout directly to != 0, he must know what he does
and not send PR int this case.
If t_timeout != 0 is needed, better way is increase it more,
maybe to 5 minutes f.e. than breaks tty.c code as occurse now.
P.S. Please not back out anything without discussion with
fix author (me) first.
