In fact, even the then part for CRTSCTS, i.e. if CRTSCTS is set, is also wrong. It says: 2020: /* raise DTR/RTS */ 2021: set_mctrl(port, TIOCM_DTR | TIOCM_RTS); A real serial port doesn't touch the states of both of those lines whether CRTSCTS is set or clear. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
