Mouse/modem port and interrupt conflicts were common among PC Access for DOS users. We expect port conflict to be somewhat less common with PC Access for Windows. Windows doesn't let PC Access grab the mouse's COM port. However, an interrupt conflict is still possible, because the user can certainly plug their mouse into COM1 and their modem into COM3.
Problem: "The mouse pointer appears in the middle of the screen but I cannot make it move when I move the mouse. I can still call into and work with the MLS but the mouse is dead." [Note: symptoms may differ in PC Access for Windows.]
Cause: Port or interrupt conflict between a serial mouse and modem/serial port.
Solution: Open the Modem Setup window and write down your current Port setting. (This will be one of COM1, COM2, etc.) Next, exit PC Access, exit Windows, and run MSD to find out which port your mouse connects to.
· You must make sure that the mouse and modem port are not the same and that they aren't both on even numbered or odd numbered ports. For example, if the mouse connects to COM1, the modem may only connect to COM2 or COM4. This is due to hardware limitations in the PC and is not caused by PC Access.
