	   Greetings, all.  

	   I got tired of typing escape-characters to emacs when I terminal to
	   unix machines from the LISPM.  This patches the telnet character
	   typein filter to convert meta-chars to the sequence ESCAPE-followed-
	   by-char.  It has probably appeared here before, but in case not, here
	   it is for anyone's use.  Please pardon the length -- it was borderline
	   whether to just post a note or include the code.


       This functionality has been included in Genera since 8.0, but it depends
       on the setting of your serial line.

    TELNET doesn't go over serial lines, it goes over TCP and CHAOS
    connections.  These are both 8-bit connections, but many Unix TELNET
    servers strip the high-order bit.

Perhaps I misunderstood what jclose was after.  He only said when he
"terminal"-ed to Unix, not when he TELNET-ed.  I won't argue Unix with
you, but many people don't know that they have to tell EMACS to accept
meta characters too, since it also will gladly strip the high-order
bit. (In GNU-emacs you need (setq meta-flag t) in your .emacs).
