Take that option out and it works. Take that option out at anytime it works. My program basic writes a few characters a serial port and then reads them back in from the same port. I have a loop back cable connected to the port. It writes the data but waits forever to read them back in >>From my tests, it appears that the termois tcsetaddr settings is not gettin= g set when I call it when this option is on.
