Really?  Turning off tty echo sounds exactly like what he wants.

Emacs shell echoes characters for you, just like interactive shells do.
When you press enter, the characters are sent to a pseudo-terminal, and
if the pty echoes them, the input string will be printed twice, as the
OP observes.  It is hard to tell what is going wrong in his setup and
whether it has anything to do with tty echoing, but it's a valid guess.
