OK, lately I have been making assertions when I probably should be
asking questions. Shame on me.

I understand on Unix, the client can open a tty, and direct the output of the inferior to it.
On windows, how would the client do that?

Does native windows actually support opening a 'tty'? Something I didn't
know.

Finally, using cygwin windows, do I use the tty option as if I was on
UNIX?

Thanks,
