Scanned my AmigaMUD docs. The main culprit was the 'telnet' that came
with the AmiTCP/IP package. You likely don't care about that one, other
than as an example based on BSD sources. I couldn't find details, but
it looks like the TinyFugue MUD client doesn't handle ECHO negotiation.

That's what I did on the Amiga, sort-of. I called the intermediaries
"agent" programs. They ran on the server machine and sat between the
real server and the client. The new version I'm working on for UNIX
does the telnet stuff right in the main server.
