[Coco] Drivewire cable question - 4-pin DIN to PC DB9

[Mark Marlette]

Chris/Al(l),
You are correct, the C9 cable is not wired for the 230K mode.
Only the three wires are connected.

    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)

I like you, but I wouldn't want to see you working with sub-atomic
