SSH help

I'm not very familiar with unix/linux or ssh, but i downloaded pspssh in hopes that i could use the telnet client built in to play some muds. I have a few questions about the app.

- If there's no login or password, what do i do about those fields?
-When I enter the address and port of the mud.
(dsl-mud.org:4000), the connection succeeds but it brings me to a blank black screen with a small white bar in the top corner. I'm not very familiar with unix, as I said, but i figured it was the command line. But nothing i type shows up.
-Does connecting to telnet in pspssh require a different procedure than connecting to an ssh server?
-If someone could give me a step-by-step of how to connect to telnet using this app, it'd be greatly appreciated, i just want to know if i'm doing it completely wrong, lol.

Thank You
