Configuring a Modem on the AUX Port?

I was just testing this and it looks like I'm stuck on number (4) in that Cisco document. I can telnet to the router using it's IP address the port and line number, but after it asks me to authenticate it says "OK" and doesn't allow me to type any more commands:

telnet 192.168.108.1 2005
Password:
OK

Here is the portion of the article I'm stuck on:


Use the reverse telnet method on the modem to configure the appropriate initialization string.

For more information on reverse telnets, see Modem-Router Connection Guide or Establishing a Reverse Telnet Session to a Modem.

    maui-rtr-10#Telnet 172.22.53.145 2065

    !--- The IP address 172.22.53.145 is the Ethernet address on the router.
    !--- 2065 represents 2000+line 65. Refer to the documents mentioned above,
    !--- if the reverse telnet fails.

    Trying 172.22.53.145, 2065 ... Open
    at

    !--- Modem attention command.

    OK

    !--- The modem responds with an OK. If you receive any other message,
    !--- or no response at all, replace the modem hardware.

Thanks for the replies...

Irmoore - Once I login using reverse telnet on the AUX port it asks me to authenticate, then it tells me my password is ok but once it gets to this point it will not let me type anything, it just sits there?

Trinak96 - I will take a look at the that article as well.

Also, although there are some good advantages (as well as disadvantages) of being able to configure the access through the console port, would rather just use the AUX port. These modems and phone lines are only being put into place for a short period of time as a backdoor during the FR to MPLS conversion.

Can you think of any reason why I can't issue any of the modem commands after authentication?

Here is the config for the AUX port:

I pulled up a telnet session to the router and then started another one using Reverse Telnet. When I issue the "show users" command I can see that I have connected to the AUX port see below:

Washington_DC#sh us
    Line       User       Host(s)              Idle       Location
   5 aux 0                idle                 00:00:16 192.168.X.X
*  6 vty 0                idle                 00:00:00 192.168.X.X
   7 vty 1                idle                 00:00:48 192.168.X.X

  Interface  User      Mode                     Idle Peer Address

On the reverse telnet session that wont let me issue commands it hangs on this screen

User Access Verification

Password:
Password OK

Once I issue the command "clear line 5" from the other session it kicks me out. I have connectivity but I can't issue any commands?

I promise that connecting to console port is easier to do, and will serve you better as remote access during a changover of services.
Here's step by step guide that I have used hundreds of times without fail. The USR init string in the Cisco document above does not work properly:

Here's another reference on reverse telnet to the modem:
http://www.cisco.com/en/US/docs/ios/12_0/dial/configuration/guide/dcrtelnt.html

The problem I'm having is that we have 3 modems.

1 is connected in Chicago office
1 is connected in the DC office
1 is local to us here for Dialing into the above mentioned offices

The modems are connected to the routers, Chicago in the AUX port and DC in the Console port.

The last document I read assumes I have local access to these modems, but I don't.

We don't have IT staff in these locations, only here at the main site.

I have never configured a router for dial-in access, and up until now forgot about the AT commands :)

I'm really stuck here, I can't dial into the routerrs and I can't gain access to issue any of the AT commands of the modems. I'm not sure what I'm doing wrong. I have followed the Cisco doc and attempted following the other one posted by Irmoore.

Can I get this to work even though I'm not in these remote locations and cannot issue the AT commands on these modems? The router sees it but once I login to the router using rTelnet I can't issue any AT commands :\

This is now critical so I'm raising the point value. I need to get these up this weekend!

Thank you ~

Looks like these issues were with the routers themselves. Thanks for all your help on this one

Marc, I am having the same issue as you.  Im prompted after the reverse telnet with a login prompt..and cant type anything after authenticating.

what was your solution?

Same issue; the problem with the routers was...???
