Port B on the Model II portion of my Model 16 supports the
following signals:
PIN#
----
GROUND 1,7
DATA SET READY 6
CLEAR TO SEND 5
CARRIER DETECT 8
TRANSMIT DATA 2
REQUEST TO SEND 4
DATA TERMINAL READY 20
If the printer does not support:
CTS then connect pins 5 and 20.
DSR then connect pins 6 and 20.
I'm sure you are aware that if no device is attached to port A
(assuming the printer is on B) you must put a terminator plug
on it. RS sells them for about $30 last I checked, or you can
make your own by connecting pins 3, 5, 6, 7, and 8 together on
a regular DB-25 connector.
Hope this helps,
