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
?
