 Yeah, COM2 and COM4 are both using IRQ3.  BUT -- I don't try to use them at
the same time.  In fact, with OS-9000, I only load one of the device
descriptors.  Messydos and OS/2 on the same box let me get away with that.  I
hate to start playing IRQ-Roulette on the 486 - everything you fix breaks
something else.

 Thanks,
 John
