My experience is slightly different but might answer your question anyway.
When I upgraded to WinXP, I kept my old serial port cards (two of
them) from my Win98 machine. This gave me two com ports on the
motherboard and two on the PCI cards. While they worked most of the
time, I had problems running MMTTY. MMTTY would work if the PTT/FSK
was set to com1 but not on any other. Other programs would work ok
on com3 and 4, but occasionally would stop responding for no apparent reason.
Long story short: I got rid of the old cards and installed some new
ones which claimed to be designed for WinXP. Problems solved. I don't
know if it was the cards themselves or the driver software that came
with them, but something was almost right but not quite.
The new cards were only $10 each, well worth the money.
