The telnet LINEMODE option (which is apparently implemented using
EXTPROC in the tty driver) is used for more than X.25 emulation.  For
random (usually old) hosts that do not perform remote-echo of keystrokes,
telnet linemode make interaction much more pleasent over long-delay
paths.  It used to be that even logging into a UNIX box could use
the LINEMODE option when the remote tty was in cooked mode.
