I actually connected the modem to a DOS machine to ATS0=2, (simpler). Then i connected it to the Port Server and as mentioned, it would not answet (DTR light on modem was off). I reconnected it to the DOS machine and as soon as i plugged it in, the modem's DTR light went on and it answered (did it while the line was still ringing).
As far as cabling being the problem, it cannot be for the following 2 reasons....
A: I'm using the same cable that previously worked with the Accelleport - I swapped directly over to the Port Server , same cable, etc...
B: I've tried using the factory DIGI RJ45 10 wire cable that came with the Port Server (connecting to ttyB14 directly on the port server) and enabling that port, and I get the exact same issue, NO DTR light.
When i arrow through the settings on the PortServer itself, and arrow to 25 (or 14 when using other cable)... The only two lights on are RTS and DTR. I'm not sure if this is reading that the modem is Ready to Send, with Data Terminal REady, or the port on the port server is Ready to send, with data terminal ready.
many thanks in advance
