How Do I ID Com Port?

Archived from groups: microsoft.public.windowsxp.basics (More info?)

If you have a modem in your PC, it has an on-board COM Port
probably on Port #1 or 3 which are multiplexed together. To get
your device to work, you'll need to reconfigure the BIOS settings
for Serial Port A to use COM2 and IRQ #3. If your motherboard
has two Serial ports (A/B) you'll want to disable A and use B w/
the settings mentioned before.
