If all you want to do is "print" to the telnet client, then
that's trivial: just accept a TCP connection and start writing
cr/lf terminated ASCII strings to it. IIRC, the client will
probably default to line-at-a-time mode.
If you want to read data from the telnet client, you'll need to
get a little bit fancy, you can add some simple-minded option
negotiation code like that found in RedBoot's net_io.c file.
If you want to get a little more fancy, I'd probably switch on
the suppress-goahead option and do character at a time instead
of line-at-atime.
