This is a mystery to me but there's no doubt a simple explanation! I have a taiwan special I/O card in my 386SX which provides COM1 and COM2. My mouse is on COM1. Nothing is on COM2. I installed an internal modem and set it for COM4. Under DOS and under Windows in "Standard Mode", All of my programs are able to use the modem. But, in Windows enhanced 386 mode, this is not so. Procomm in a DOS window can dial a number, but once the call is connected I can get no response. Remote2 says it's dialing but nothing happens. Windows Terminal says "COM2 is in use by a DOS Application", and is unable to reassign to another port. Is there a solution, short of pulling a chip out of my I/O card in order to disable COM2?

Try configuring your modem as COM3:.
