Hi,
 If you wish to listen to telnet connections on a different port than 23,you can do that using range 3000 to 3999 with rotary-group AA.
You will have a listener on port 30AA.

Here is the link:

and

To access async lines directly on a terminal server, 2511 for example, you can telnet to 20XX on which XX is the line number.

Sometime ago I found a link to a great table listing the ports and their connection types, but with new search engine, I do not find it anymore...
:p

That did it, and it worked. Thanks, Ivan. However, I do remember
somewhere where you could connect to a port using the 2000 range. Any
thoughts on that one?
