I have a 2520 which I am trying to configure with a external analogue US Robotics modem, to allow me to dial in and connect to my network from a dum terminal. I have the modem connected to serial 3, but each time I try to dial in the modem just ring and dose no answer.
Can anyone help.
Thanks

The output from Sh line 2 is below, I noticed that on your sh line you have Status: No Exit Banner, Modem Detected, CTS Raised where as my sh line has Status: No Exit Banner dose this indicate that the cable may be at fault ?

Neil,
as You can see here,
Modem hardware state: noCTS noDSR DTR RTS
Modem type is unknown
Your modem is not detected and configured by the router, thats why it is not answering Your calls.
You either have faulty or incorrect cable, faulty modem or there is a speed mismatch between modem and Your router.

Giedrius,
Thanks for all your help.
The problem was down to a faulty cable between the modem and router.
Thanks again
Neil
