XP is no problem. I have a system with 10 comports under Windows XP. (one card with 6 comports, one with 4)

Easiest is if you buy cards with moschip (MCS) 9845/65 (PCI) or 9922 (pciex).

Many companies like Sweex and trust have cards with these chips, and they are generally very well supported by various windows versions (including 64-bit Windows including win8) and *nix.

IIRC the PCI chips (98x5) came with dos setup utils. The only pciex brand that I have (MCS9922 based) doesn't seem to come with them though.
