I've recently started messing around with Java sockets and telnet...

I want the user to be able to connect to the server, just type a letter and have it sent to the server, without pressing enter to send it. I'm sure there's no way for the server to set this up, but maybe telnet has a parameter or something which could allow this?

Maybe if I got the user to type stty cbreak or stty raw before running telnet, this would work? (UNIX only, I know!)

If I can get telnet to do this then it saves me having to write a special client just for this feature...
