I'm using an old laptop and I want to use a serial mouse instead of using the built-in touchpad of the laptop I'm using. There's no problem on BIOS setting of the laptop regarding input device configurations, all settings on the BIOS are correct. I plugged-in the serial mouse on COM1 on the laptop before starting it to run. After knoppix finally loaded and ready to use, and as I move the serial mouse, it doesn't move the mouse cursor, but when I use the touch pad of the laptop, the mouse cursor moves. What shall I do? Help please... I'm very new to Linux.
