You do realize cygwin apps run just fine from the regular windows
console, right? You can even invoke your favorite shell to run
scripts.  So if you were trying to run native windows console tools
while using cygwin tools as well, this might be something you would do
(for instance running a batch file or sysinternals tool or something
similar and using some cygwin tool like grep).  I can't speak to the
cygwin=tty thing though.
