You can try it out at WR3D (fast) GB7DJK (slower reference site). Log in with your callsign. Unfortunately, because there seems to be a divergence of view between various telnet clients as to whether they echo or not, I have set the default to be 'remote echo'. If you use one of those telnet clients that actually obeys the rfcs (eg a unix telnet) you may feel happier doing a set/noecho after you have logged in.
