I can save you a some time, I think.  The Spinwriter 7700 family
hardware handshakes on pin 19 (Secondary Request To Send).  To set up
a cable, you should connect pins 5 and 6 on the computer side to pin
19 on the printer side.  A diagram for it looks like this:

Computer       Printer
TD  2  <----->   2  TD   (straight through)
RD  3  <----->   3  RD
SG  7  <----->   7  SG
CTS 5  <--,
DSR 6  <--|-->   19 SRTS

Sorry for not noticing this the first time :-).  By the way, I found
this out the hard way (I'm not really a hardware hacker), even though
I had the Spinwriter manual right in front of me.  What a drag!
