Has anyone here been able to connect a modem to the console/aux port of an 831 router and cleanly dial into it to get to the exec prompt? I have done this on many other routers with no problems. I seem to get a lot of garbage characters when doing this on the 831 series routers. I have a tac case open and they have suggested numerous modemcap entries to try but the result is the same with each of them. I would just like to know if anyone else has been able to make this work on an 831 router. I've tried using USR Courier and Sportster modems.
I do not know which IOS version you are using, but check out this sample config for a 831 running 12.2 (in this example the AUX port has been configured for dialin and dialout). You might have to specify the speed and stop bits in your AUX port config:

The following example configures dial backup and remote management on a Cisco 831 router.
As a matter of fact, I have done this plenty of times using other model routers. I was hoping to find somebody who has actually done it successfully with an 831. I bought three of these routers and have not been able to get this to work cleanly on any of them. I have even upgraded IOS on one of them thinking it might have been an IOS bug.
stupid question maybe, but what kind of cable are you using ? The cable that is actually used for connecting the modem to the console/virtual AUX port on the 831 is Cisco part number CAB-CONAUX=, straight serial cable - RJ45 to DB25 male.
