Telnetting to IRC

ok, my university has blocked port 6667 (used to IRC). but I can use a remote PC and from there I can use port 6667. Since no IRC client is installed, I have to use telnet. Does anyone know how to use telnet to use IRC? I have googled for articles, but I can't find anything that has helped. I usualyl get a "you have not registered" error. Basically I need to be able to choose my nick, and:
/msg nickserv identify password
and:
/join #channel
and of course talk.

Does anyone know how, or can you direct me to a good article?

see if there is an IRC program on the server. my isp used to have one, but i forget what it was called. maybe mirc?

I've checked and there isn't one.
