This is a direct US Robotics modem to 2950 console connection (no control port manager). I've tried following the "dial-in router" guide and the "Connecting a Modem to the Console Port on Catalyst Switches" guide, but haven't had any success. I did find some modem command lines when attempting to config the console, but the switch tells me it's unsupported:
% Line 0 does not support modem control
ANY IDEAS WOULD BE GREATLY APPRECIATED!
