This is a problem caused by this change: http://cygwin.com/ml/cygwin/2004-10/msg00364.html And, then, the problem was noted here: http://cygwin.com/ml/cygwin/2004-10/msg00904.html The problem is that cygwin is now behaving like linux in that timed reads from a pty/tty work correctly. It is not behaving like linux in that once you get an EOF on a read using stdio, you get EOF forever after. I've made a cygwin-specific correction to the newlib library to make cygwin work more like linux. I will generate a cygwin snapshot sometime soon which should have a fix for this problem.
