RE: Modem to Console Port
It is possible. There is actually no configuration on the router. You will need to set the modem to talk at 9600, 8, N, 1 with no local echo. You also need to set the modem to auto answer. Your modem should have documentation with the proper "AT" commands that you will need to issue. Save this configuration to the modems NVRAM and plug it into the router.

RE: Modem to Console Port
John brought one thing to light that I forgot to mention earlier. By connecting a modem to the router, you are opening a security hole into your network. Make sure to set a timeout on the console port so that when a user hangs up, the console session will timeout and another user can't come in behind you and grab your console session. You may also want to have somebody at a remote branch physically unplug the phone cable from your router after you have completed any configuration changes. Better yet, control access to your routers with Cisco Secure ACS. You can then set privilege levels on a user by user basis as well as logging access to your networking infrastructure. Hope this helps...

RE: Modem to Console Port
Also another note if you are going to connect an OOB modem. You may want to configure the modem to pick up after like five rings. That way if a hacker is using a dialer program looking for modem tones they usually don't wait more than 2 rings before it hangs up and tries another.

Re: Modem to Console Port
Jason, Thank you very much. The dip switch settings did the trick. I am installing these routers remote and from time to time when we turn up the circuits something doesn't work right. So, I ship a modem, have the customer plug it in to the fax machine jac and bingo, I can config it just like I was setting there. That way I don't have to be on a plane for a day and a half for a 5 min job.

RE: Modem to Console Port
1)Connect the modem to a PC 2)Set the dip switches on the modem to 1,3, and 8 down, all the rest up. 3) Power on the modem 4) Begin a terminal session (9600,8,N,1) 5) Type AT and you should get an OK from the modem 6) Type ATFW0 7) Type ATI4 to get the current modem settings 8) Copy the following string on the terminal (this will also write it to the modem's NVRAM) ATE0F1Q1I0H0K0A0B1N6C1D0W0 (Note: This turns echo off as well, so you won't see any further commands you type.) 9) Type ATI4.

Re: Modem to Console Port
All good advice, but at the least issue 'disable' when you're done so that privileged commands cannot be issued, and use exec-timeout in case you get bumped off your phone line and can't get back in right away. -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ Cisco resources: http://r2cisco.artoo.net/ ""Chris Lemagie"" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
