I think we're both assuming what the user is doing and the reasons as to 
why. Let's just agree that:

1. Telnet can use any ports providing the user redirects.
2. Telnet passes clear text no matter what.
3. ssh ought to be used to replace Telnet whenever possible.
4. ssh also can be made to work with any port other then 22
