FWIR from what I recall, you have to create and open read and write file descriptors using the 'msvcrt.get_osfhandle' function, and pass them to the subprocess on the command line. Or you can pass the handles. Then you get a communication channel that is not STDIN. I have no idea why the designers did this. I've submitted a patch, and received 0 attention on it. -- http://mail.python.org/mailman/listinfo/python-list
