On my DELL Latitude XPI+ P133ST running MSWin95 v 4.00.950a, when trying to open the file "com1" or "com2", the program hangs in open(). The behavior is the same with or without the O_NDELAY (or O_NONBLOCK) flag in open. Sample C code that reproduces the problem on my PC: #include main() { int i ; i=open("com1",O_RDWR | O_NDELAY,0) ; } -- Laurent Montaron sylvestre@world-company.com 75005 Paris, France, Europe meow@pobox.com Planet Earth, Sol III, South-West Milky Way Le_Chat on IRC/EFnet Universe E45-A North, Continuum 28 PGP key available - For help on using this list, send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
