The only other way I can think of to test the port without a modem is 
another computer.  Hook-up two computers via a serial cable.  You can 
use some sort of terminal program, like minicom, to establish 
communications between the two computers over the serial port.

Basically, you just want something you know works on the other end of 
your serial port, to see if you can get it working.

Unfortunately, I don't have much experience with serial mice.

Have you checked that your serial ports are enabled in your BIOS?
