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.
Do you use tcsh "lineedit" mode? (I assume that, like many people,
you probably have a slightly different login environment on paris.)
If so, try turning it off. It disregards the tty modes (or rather, it
records them and changes them to suit itself) for processing its own
input.
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.)

Hmm... perhaps "stty nl" would help?
