It has the usual hack of selecting line or character mode based on the
echo option.
As a reminder, I'd still like to see a MiamiTelnet option to negotiate
remote echo actively rather than passively. This is needed for
compatibility with Telnet<->serial passthrough on DECservers. The problem
is that the DECserver itself isn't echoing, so it doesn't send WILL ECHO,
but the system at the other end of the serial line *is* echoing. The
DECserver does respond to DO ECHO with WILL ECHO; it just doesn't initiate
it. Theoretically it should always be reasonable to send DO ECHO, but
that would cause problems with other servers broken in other ways. :-)
