Microsoft has a standard interface called InPort.  It is usually
implemented as a card that goes into a slot in the machine.  The
so-called "bus mouse" connects to this interface.

The serial mouse connects directly to the serial port and draws
its power there.  The major difference between these mice is that
the logic is on the board for the bus mouse and its case is almost
empty.  The serial mouse is jammed with electronics that control
its function.

As to the problem of getting Windows to recognize your mouse
on COM2, you might try going into Windows Setup and changing
to the MouseSystems driver for COM2.  I can't guarantee that this
will work, but you might try it.  It sounds like a situation
that the Setup people didn't anticipate.
