Force telnet client into character mode

Question

I have an application where I accept a socket connection from a telnet client and put up a simple, keyboard driven character GUI.

The telnet client, at least on Linu

Answer 1

Interesting. I had more luck sending

IAC WILL ECHO IAC WILL SUPPRESS_GO_AHEAD IAC WONT LINEMODE
255  251    1 255  251                 3 255  252       34

The IAC WONT LINEMODE seems to be redundant: my telnet client seems to get to the right state without it, but I left it in for completeness.
