Sounds as if perhaps bytes are languishing in the fifo. If that is the
problem, /sbin/setserial <device> low_latency
for each port might make it work. That and, if you can't use canonical
input, - what _does_ constitute a packet? Set MIN and TIME to take
account of it. I guess maybe MIN 1 and TIME a bit longer than one byte
takes at the line speed.
On just about all UART's, characters in the FIFO get flushed after four
character times. Since Jean-Marie Bussat said that the baud rate was
4800, that means that if no characters appear after approximately 0.01
seconds, a receiver interrupt will get posted and they'll get read by
the user mode program.
There's something else going on here (like the ICANON flag being set,
for exampple), or perhaps somethign with the setup of the hardware
that's causing the problem.
