Be careful with locale support. Some of them, notably russian/ukrainian
(cyrillic in general), use the escape character as A CHARACTER, so you
have to escape it too - it's just not obvious for those who speak
English :-)

An idea for you (that's how I implemented it): telnet protocol handler
is a container, and options are the objects, so as you add the option to
the container, it automatically CAN/WILL it (depending on the context),
and if you remove it, it CAN'T/WON'T (side question: are all telnet
clients/servers safe to the attempt to renegotiate the options not at
the very start of the session, but somewhere in between? Guess most of
them, because otherwise it would be a pain in the neck to resize the
Xterminal...)

That's if I remember my implementation right :-)
