Hi,
Hope you can help me with this, Im stuck.
I have a 2500 router with several external modems (US Robotics 56k) connected over asynch cables. the line config is setup to autocommand telnet to a backend server.
When I attempt to dial in, whichever modem answers, it seems to pick up the call, but then it drops almost immediately. The router log shows the same debug message each time:
