Any examples of it, so that I can understand it would affect me? > I can't tell the exact application. Just from the source code, I made a guess. The original code considers the M_DELAY, M_BREAK and a set of other Control messages which require serialization. If we totally overlook these conditions, it may cause problem. There are so many serial applications and the termio(7I)/termios(3C) are also complex, we are not able to test every corner case at this moment. So, to be safe, I think we should take a conservative fix.
