edit control character negotiation?

[Jordan Brown <[e-mail]>]

Having just bumped into it a few times, I've noticed something that telnet
really "should" have a negotiation for.

We have a terminal type negotiation, but how about a negotation for what
character should be used for "backspace", "kill line", etc?  Yes, these things
are (sort of) negotiated in LINEMODE, but not really in the same way.  One
would like the client to tell the server "we would like to use Del for
erase-character".  On UNIX systems at least, this could be easily implemented
in both client and server.

Perhaps it should be bidirectional, so that a server that knows its system
can only handle ^H can say "if you want to erase a character, you better
send me a ^H".
 
Thoughts?
