Hi Samuel, The RFC for telnet is 854 -- you can get it from www.faqs.org, or from the internet society (www.rfc-editor.org). From memory (I can't find my copy of the RFC at the moment), the protocol is fairly straightforward. There is no need to negotiate options, and you should be able to just send straight text. The Telnet protocol defines something called an 'NVT' (Network Virtual Terminal), which defines the characteristics of the control characters. Also, at the top of the 8-bit character space are some reserved characters -- from memory, it is just the byte 255 -- check RFC 854 for details. If your just using straight 7-bit ascii, you shouldn't have any problems. Also, java uses unicode (16-bit) character encodings natively, so you'll have to tell java to convert its characters into ASCII. I've forgotten how to do that, but the JDK docs should tell you.
