There is no real-time driver for the moxa 104 that anyone has
announced. You have two choices a) port the moxa 104 driver
to real-time or have someone else port it, or b) use one of
the multiport boards based on standard PC UARTs (8250, 16450,
16550, etc.). It's been a few years since I've used multi-port
serial boards, so I can't recommend one off-hand.
