Again sorry if this is already covered.
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 <fcntl.h>
main() {
int i ;
i=open("com1",O_RDWR | O_NDELAY,0) ;
}
