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

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.

Detail:

Here's the cygwin log:

PS i can run unison and sftp fine in cygwin. Together with the fact
that emacs shell running unison or sftp works fine on OS X, i presume
this must be a emacsW32 or emacs on Windows issue. On the mac, i'm
running a version of Carbon Emacs that is based on emacs 22.x, so
possibly the problem could be emacs 23 itself...

thanks for any tips.

More likely an issue with basic incompatibility between Cygwin
emulation of Posix terminals and the way native Windows Emacs runs
subprocess via pipes.

Will the coming release of Cygwin 1.7 some day now change this?  The
news for 1.7 talks about "reworked pipe implementation", but I have no
idea whether this makes communication with Emacs better.
