Does anyone know what pins to use for RS-232 I/O?

The S-700 side of the connector has two separate sets of data
connections,
one for
the keyboard/printer and one for the acoustic coupler. An option was a
cable
which branched to two DB25's for connection to each part of the
terminal.

I have the manual and could scan some more pages if necessary.

So one needs to jumper the 15-pin cable at the back? I've never seen a
TI *with* the thing! (I've seen 3 in very varying condition)
I was recently lent a TI 745 - and it doesn't even paper advance. On
Line does light up when I whistle.
How do you take it apart? I am trying, but... :)
