I am using windows xp.  I have an internal usr263095 modem.  On an old win 98 machine i saw that the modem was using virutal com 4 that was created with software program and not actually showing up in the device manager.  I am trying to set up virtual com ports in xp but they just keep not working.

I have assigned unused IRQ's to them, changed the I/O's and they just won't work.

Does anyone know of a solution? Or of a software program that would create the virtual "virtual" com ports?

Only the modem's own driver can create the proper virtual COM port, as it's highly brand and type dependant. Try downloading an updated Windows XP driver for your modem. You can get it from here: http://www.usr-emea.com/support/s-prod-template.asp?loc=mest&prod=3095

Verify that this is a fake modem (winmodem) before going into creating virtual COM ports. COM 4 is actually reserved as the label for a hardware COM port.

Is the modem not working correctly if it is installed by XP's default drivers? I wouldn't change a thing if it was working correctly without any conflicts.

Nothing worked.  I just gave up and used a different motherboard and it worked fine.  Thanks for the help.
