I thought by purchasing a bus version of the Microsoft Mouse, I would be
able to continue using both COM1 and COM2.  Turns out that the recommended
interrupt level for the mouse when installed on the PC/AT is the same as
COM2, thus (I think) preventing simultaneous use of the mouse and COM2.  I
have an IBM serial/parallel card as COM1, and an AST Advantage with a
disabled COM2.  Is anyone familiar enough with the AT's interrupt levels
and its complement of available hardware to suggest another interrupt line
which I could use safely with the Microsoft Mouse?
