1. The command "stty -echo" doesn't seem to do anything on the RT;
the echo mode acts as if it is permanently wired in the ON position.
On a VAX (I tried only paris, not a microvax) it properly turns the
echo mode OFF.
Echo mode isn't often switched off within Athena, but the version of
telnet I am using is designed for satellite hops and long-delay links,
so it works in local echo line-at-a-time mode, for which one prefers
to turn off the second echo from the tty driver.
2. Every line sent by an Athena RT on a telnet connection is ended by
two or more control-M's preceding the control-J. The Athena Vaxes
send exactly one control-M every time. (Noticed while the machine at
this end was in debugging mode.)
