using NS16550A UARTs with a dumb serial card (386/ix)

[Witold Paluszynski]

I have an Everex EV170B IO card with 3 serial lines on it.
I just tried using it with the NS16550A UART chips, which
have FIFO queues for TX and RX and are supposed to be supported
by 386/ix.  No go.  It doesn't work.  What is strange is that
a while ago there was an article here from someone who reported
success with this card and UARTs.  If this combination can be
made to work then I would appreciate it if someone told me how.

Thanks,
Witold
