Telnet: Sending an output to the connected host.

Question

Hi all, I have written a GUI to connect to a host using a socket. This is going to be a MUD client (for all who know what a MUD is) and I can't seem to send anything to the host. Any suggestions? Also, the code returned by the host is in some computer language at some areas. Like when there is supposed to be colour it shows a squarebox then [32mL.
This is the complete working code.
Thanks.

Erm I got it to work using PrintWriter already thanks..... Though I need help about how to import the colours and such, and I do get some weird characters like Ys with some dots above them. Any suggestions?
