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?
