I remember a fix a LONG time ago (maybe on the 36) where you had to physically 
break off a pin on
the cable to get something to work.  Maybe one of my coworkers remembers this.  
I remember asking
someone, "Did you break off pin xx?"

Subject: DTR won't come on for Auto Answer
I'm making some progress with this ECS modem I'm using  (MultiTech
MT2834BA).  Calling out to IBM with the QESLINE is working.  I created
another line that I would like to use to call into the 400.  I get a connect
pending but I never get a TR light on.  In order for the modem to answer the
line I need the TR light on.  If I disconnect the 400 cable at the modem end I
can see DTR pin 20 go high when the line is varied on (so I believe the 400 is
configured for auto answer ok).  When the cable is connected to the modem it
won't.  I seem to remember a problem like this many years ago with IBM
boxes.  I seem to recall one of the pins on the modem had to be low before for
the 400 would bring up DTR.  I don't recall which one it was.  Does
someone remember the required sequence for the 400 to bring up DTR?
