Thanks.

I was able to go to the local computer store & geta PCI card with 2 serial
ports on it. Disabled the onboards, pluged it in, and it "just worked".
Suprised me, to, since  I was concerned when I took it out of the box, and
found no way to set IRQ's etc. I guess PCI really is "a good thing".
