problem with ssh/sftp/unison in emacs shell on Windows

[Xah Lee]

looks like emacsW32 have problems running sftp or unison.

the problem with both is this error message:

 bash: [4972: 1] tcsetattr: Inappropriate ioctl for device

is there some terminal setting or something in emacs to get this to
work?

unisone has a -dumbtty option, however, with that on, still same
error. So, apparently, it seems the problem is with emacsW32 or emacs
on Windows somewhere. On the Mac, I'm able run unison, rsync, sftp no
problem inside emacs's shell command, and i don't recall having to
setup setup anything particular...

possibly i need to tweak some termcap in cygwin??

Thanks.
