Description Matt Wilson 2002-10-08 14:08:08 UTC 
POSIX states that if optional_actions includes the TCSAFLUSH flag "the change
shall occur after all output written to fildes is transmitted, and all input so
far received but not read shall be discarded before the change is made." 
Current kernel behavior flushes (discards) output when you call tcsetattr.
