[Coco] Disto SC serial port

[Roger Taylor]

I'm looking for the specs for the serial port on any of the Disto SC 
adaptor boards.  I think mine is the 3-in-1.  It has a clock battery 
and the 17x2 header mounted on the side.

I do believe the pins of interest are going to be the 4x2 set apart 
from the 13x2 pins, but trial-and-error finding which ones are for 
send/receive/ground/dtr isn't possible without knowing how to read 
the signals in the CoCo.  Any help would be most appreciated.
