sounds like a multiple problem: mouse and modem.
Navigating a new GUI, if your mouse bound, is like committing suicide with a plastic spoon.
Pull the modem card!
solve the mouse problem first! Mice come in 3 flavors: serial, PS2, and USB. You already said you were connecting to serial.
Your Mother Board (MB) probably supports PS2. See if you can buy(get) a PS2 mouse connector. They generally come in 2 flavors 4 pin in-line or 8 pin in-line. Look on the MB around where your keyboard connects. ID the type you need. If you need to know how to ID pin 1. Post back here.
If others here have had good luck serial mice then follow them and disregard this message.
