There is a public domain driver floating around that works well under
386/ix (so I've been told).  I've played with various smartcards, and
haven't found one that works correctly with multiple bi-directional
modems - so I ended up with a dumb 8 channel serial card (Hostess)
with 8250 chips - and I run 4 high speed modems all locked at 19,200 -
and I haven't had a single problem.  I've sent a couple of messages
off to SCO asking for 16550 FIFO support in their drivers - and still
no reply.  Maybe if others join in with the message writing they will
add FIFO support in the next release (Amy?)
