DTR won't come on for Auto Answer

["Gary Kuznitz" <docfxit@xxxxxxxxxxx>]

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?

Thank you, Thank you, Thank you,
