Hi all,
I need to write(2) a certain character to a serial device (using the standard /dev/ttySx), and make sure it was transferred to the device before I continue. I tried fsync(2), but that failed (does fsync even apply to character devices or only block devices ?).
Any idea ?
Is it even possible or should I just usleep(500ms) after write(2) ? (I know, it's ugly..).
Thanks in advance, Naziir.
