I am trying to congire a 1800 router to allow modem "out of band" access.
I have configured the AUX port on line 5:
line aux 0
transport input all
I also attach a file with the sh line 5 output
internet-gw#sh line 5

I have US Robotics modem connected externally, when I try to dial it I get no answer.
If there something I am missing?
Do you mean that the call keeps ringing out ?
If so, then the problem is on the modem not the router. I would connect to the modem's serial port via a terminal emulation program and issue the AT command that configures it to answer after 2 rings or something. You will need to consult the modem manual for the AT command appropriate to the modem.
I am now able to reverse telnet to the "modem"
If I run "at2 commands i get, ie

Strike a key when ready . . .
Does that indicate that the router and modem or talking?
It does indeed...
Now if you type in 'ATS0=2' that should configure it to pick up after the second ring. Then enter in 'AT&W' to save the settings.
Then, try calling into it again..
Your modem seems to be configured for a speed of 57600 whereas the aux port is configured for 115200. Can you configure the aux port speed to match the modem setting ?
I get this output whilst connected to the modem
etc and no login prompt on my terminal session.
Current setting in config
line aux 0
modem autoconfigure type default
transport input all
I also attach a copy of the output from "ati1 -11" commands in file.
we swapped the modem and it worked at first. It seems very hit and miss. Does anyone know a good modem that works well with the aux port?
