There is an application note from National Semiconductor that describes how to make a computer mouse using one of their COP8 microcontrollers. The micro described has no special built-in RS-232 interface, and I'm sure that you can strip useful information out that is relevant to interface to a PIC. Go to the National website and do a search for "AN-681".
