Read <http://cygwin.com/cygwin-ug-net/using-effectively.html#using-console>.
Then add this fact - the SSH server uses ptys.  So your program will not
work with a single character put in the input buffer.  One could
envision using 'yes' to fill the buffer of the pipe that the Windows program
interprets the pty to be.  Perhaps a nicer alternative is to build the
problematic program with Cygwin, if that's an option, so that it will
understand the pty.
