The older "optical" mice (which used a grid to measure things) were
very repeatable and accurate. As a sensor to ensure that you are not
losing lots of steps in a long slew, not at all a bad choice.

The newer optical mice (with CCDs) may be okay, but I don't know. I
just use them.

Many of the USB mice come with PS/2 adapters which use a serial
protocol, just not RS232.
