- I have my mouse set up on IRQ 2 and my Scanman on IRQ 11. I
- haven't had any problems using the two devices at the same time
- (although this might be expected, since I think IRQ 2 is actually
- the cascade for IRQ's 9-15 or whatever the upper limit is). I don't
- know anrthing about configuring the Serial port as IRQ 2, though.
