No I don't.  Interrupt signals on a peecee are active logic, not wired
or.  If you try to put multiple peripherals on a single IRQ you create
bus contention.

You can throw as many dumb COM ports into the system you'd like, as
long as you have unique interrupts and i/o addresses for each.  SCO
configures in only the first two COM ports - the rest you need to add
yourself.
