Subject: Visual C++ apps in a "telnet" window
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

(Message used to be Visual C++ apps in a bash window)
Thanks for the reply, Earnie.

Replacing tty with notty in CYGWIN variable did the trick for the bash
window.
However, it doesn't work for a telnet window started from inetd.
Any ideas?

Regards,
Ian Collins.

===================================================

Does your CYGWIN environment variable contain "tty"?  If so, this is
most
likely the reason you can't get it to work.  Either remove tty or use
the notty
switch.
