How to change interrupt numbers for COM ports on PC.
Posted on 1998-07-06
Running Windows95 on a 486.
I have an internal modem that I would like to have on COM3 or COM2. The mouse is a serial mouse on COM1. When I check the interrupts for these ports it is set to 4 for COM1 and COM3 and 3 for COM2.
When I use COM3 for the modem the program that uses the modem thinks that another program is already using the modem and tells me to close the program to use it. My conclusion is that modem and the mouse distubs each other since they have the same interrupt numbers.
When I use COM2 for the modem the entire computer hangs which is strange. Someone told me that perhaps both COM1 and COM2 is dedicated to the mouse.
I hope that the solution to the problem is to change the interrupt number for COM3. Is that correct? If so, how is it done?
Thanks in advance,
