I'm putting together an older system that has a serial mouse connector. I bought a serial adapter for use with my ps2 mouse. It doesn't work. I've tried 3 different adapters and 3 different mice, 1 generic, 1 logitech and 1 microsoft. I must be doing something wrong. I tried the mice and adapters in a COM port in anothe system as well, didn't work there either. any ideas? thanks all
