Simply enter the IP and the port number, when the box is supposed to come up about the QuestNet version, just type /n and you will enter the game.

I'd find it very hard to play a game like that! Not only do you have all the QuestNet protocol commands everywhere, but every time you press a character it's run as a command. Not too many games are playable using only one-character commands.... proper Telnet support is a planned feature.

Well my friend made his own telnet client and it doesnt process a command strait away, you can type before you enter.

I can't get it to work using a standard Telnet client though, unless there's some Telnet setting whereby you wait until pressing Enter to send the whole command.
