Emacs' `shell' sets $TERM to "dumb", which isn't what mosh expects. Try
"M-x ansi-term", and call "mosh mymachine" from there. This works, at
least for me.

Same reason. Teach your .profile or .bashrc or .zshrc not to use escape
sequences. Use something like this:

if test $TERM = "dumb"
   # set prompt w/o escape sequences
else
   # set default prompt
end
