comp.emacs (or comp.emacs.xemacs) is probably somewhat better. I've
xposted, and set followups.

That seems to work for me (well, I replace the command with 'echo hi',
and hi gets echoed).

You're thinking about this wrong. Go into the shell buffer, and type
C-h k RET
you'll see that when you press return, you don't actually insert a
newline. You call the function #'comint-send-input, which inserts a
newline, and sends the current line to the process.

So calling the function explicitly is probably the best way.
If you want divine justice, die.

emacs lisp entering a carriage return into a shell

1. shell shows carriage returns

I've got a user who runs emacs in an xterm on his Solaris 7 machine (emacs
20.4) and runs a shell within the emacs window.  The shell echos his command
and shows ^M's after every line ala':

file1     file2    file3^M

It's not a showstopper for him, but it's annoying.  Can anyone help me
with this?  (I'm rather green on emacs usage)
