Installed a network card on a 486 and now the serial mouse doesn't work. Installed a new serial port card, and the mouse gets detected, but still doesn't work. When I look under modems, I see all the com ports and the modem, but I also see serial mouse on com 1. When I test the com ports it says com1 is busy. Win 98

First of all when you look under modems there should only be the designated port listed. From the sounds of it there is a conflict between the modem and the mouse. Make sure you remove all other port under modem so to free up resources for the mouse. Now remember that com1 and com3 use the same IRQ and same goes for com2 & 4. So if the modem is on com2 that should be the only one listed under modems. Your mouse should then be on Com1.

Thanks. I ended up deleting the ports and redetecting them.

Answer 1 is on the right track, you are having resource conflicts. You may have to go into the BIOS and set the address/IRQ's on the serial ports there in order to get the resources freed up in addition to deleting all the extra comports/modems. Reserving resources may also me necessary.

An alternative is to change the resources used by the network card (is it jumpered or settable via the control panel system applet!)
