    I _think_ that was a custom mod (connect the other pin to RX to
generate an irq when data comes in?). I'm pretty sure the Cloud-9 cable
does not have it.

    Hopefully Mark can chime in and verify (or correct) my assumption.

    I believe that it should work. There is a driver/descriptor pair to
connect a terminal ti the bit-banger port. (scbbt.asm and t1_scbbt.asm)
