If you use Cygwin ssh, why not use Cygwin Emacs ?
I tested (Cygwin's) ssh from within (Cygwin's) Emacs and it works
VERY well on both Emacses (the one distributed with Cygwin - 21.2,
and cvs's Emacs - 22.0.50 built on Cygwin).

I don't use NTemacs (I stopped using it after 20.6), but I think
you should try running ssh -T (Disable pseudo-tty allocation),
something like: ssh -v -T YOUR-HOST "/bin/bash -i" .
You won't have "job control" but otherwise it should work well.

I did the same test a while ago, it works indeed without any
problem. But: it isn't because of me. It's because of Tramp users, who
apply both NTemacs (or nqmacs) together with Cygwin's ssh. And before
I discourage them for this combination, I'ld like to know that it
really doesn't work. See the discussion in
<help-emacs-windows@gnu.org>, where this thread did start.

Thanx for the hint. Unfortunately, it doesn't work either ...
