Telnet client "command" control

[nima0102]

Hi
In our project I have to write one telnet client. according to RFC of telnet, in order to connect to telnet server,client has to send some "control command" to server.
Is there any sample for these commands?

Thanks in advance

PuTTY is an open source Telnet client:

Also you might want to google around for "Telnet Protocol".
