2600 Terminal Server Connects to Loopback Not Async Port 2033

Level 1

Sorry to beat a tired horse but I have two different 2600's doing the same thing. I have followed the basic configs (this isn't that difficult) but each time I type my ip host name the session telnet's to the Loopback address. Basically it telnet's to the terminal server itself not the async port. I have reviewed these URL's.

https://supportforums.cisco.com/discussion/10790871/access-server-2511-cant-access-routers-switch

I have two 2600's one is a 2621xm running  12.4 the other one I will post here is older 12.1 but  the config is very similar. The Async ports I want to work are 33 - 35. They are connections to  DragonWave RF radios (which use a cisco serial cable) on it's 19200 N, 8 1 console port. I have tried transport input telnet and all.  I know the DragonWave console port is fine  as I can talk to them with a cisco console cable @ 19200 N 8 1 from my laptop.

Even if I unplug async cable #1 which tty 33 aka 2033 from the DragonWave  I still get a telnet login to the terminal server when I enter dw1.

Any thoughts?


TCI-Terminal_Server-#2#dw1
Trying dw1 (10.10.10.10, 2033)... Open

# Everytime I enter dw1 or dw2 it connects me directly to the terminal server (login screen) instead of sending me out async port 2033 to the DragonWave 19200 serial port. I can easily tell by the Banner MOTD and the username prompt from the terminal server. I  can log into the terminal server directly by entering dw1. Why would that be??

#While connected the terminal server I cntrl shift 6 x back to the terminal server and look at the show  session & show line . I see that it is using the session and line. See below.

Hello,

your configuration looks perfectly ok. The only thing I can think of is to add 'flowcontrol hardware' to your lines

What happens when you type e.g.:

telnet 10.10.10.10.2033

?
