JDR Microdevices has an 8-port PCI card for $128. Look for item MCT-P8S-1. I
noticed that they also have a 4-port ISA card, too. That's $48 (item
MCT-4S-1).

I have a great multi-port (8) ISA serial card
that's super
easy to configure. It uses standard 16550s mapped to standard base
addresses and uses one interrupt. You can even chain up to 4(?) more
cards to it that share the same interrupt. It has an external connector
(something like a DD-50) that then plugs into a breakout box where you
have all 8 ports as DB-25s. It's a generic board and I don't have any
info off-hand to help you find one but if anyone's interested then e-mail
me and I'll find out where you might be able to order one. I'm sure they
turn up on eBay from time to time as well.
It's called the Decision Computer Group PC-COM ISA Bus 8 port RS-232/422
card. Here's some technical info:

Here's their website apparently:

Not sure how you're supposed to order one. I used to buy mine through the
same company that wrote the C serial port library I used.
