I don't see how we could accommodate this without switching the console to "uncooked" mode. And, as you say, that would have massive effects on the console code. I don't think it's worth that much change for such a relatively unused feature. Especially since it would make console I/O slower. That said, I think the bug should be closed WONT_FIX. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
