(I'm going through old bug reports that unfortunately got no response at
the time.)

I tried `M-x telnet' with `telnet-remote-echoes' set (and the other
variables also have the values described), and everything looks normal
to me.

I'm not sure what problem this bug report describes -- I have no mouse
highlight in the *telnet* buffer, and I'm not sure what that has to do
with do with `C-c C-p' (`comint-previous-point').

This is with Emacs 28, though, so perhaps what's being described here
has been fixed in the 11 years since this was reported.
