The Modem on my PC is currently assigned to COM5. I need
to change it to COM2 or COM3 due to an application
limitation. In the device manager modem advanced tab XP
shows COM1, COM2 and COM3 'in use'.
How can I determine which application is using these COM
ports?

Com1 and Com2 are likely the physical com ports on your computer, so the
easy way would be to figure out what you've plugged in to the ports. Look on
the back of the computer :-)

Of course you could somehow have assigned com3 to a physical port, or you
could have an add-on serial card on the computer. Have you installed one?

If you're NOT using any serial devices, you could just disable com2 in your
bios, remove the modem and the com ports from the device manager, let
everything re-detect, and the modem should end up on com2 or com3. Actually,
the default is com3, so even if you had com2 enabled, the modem should have
gone to com3, unless the modem is set for com5 by default, or something else
got mucked up during the install.
