Hi Geert,

just SCIF

Upon calling open() on the tty device sci_set_termios() and sci_set_mctrl() are called in this order.
When issuing changes (baud rate, CRTSCTS...) only sci_set_termios() gets called.
On calling close() sci_set_mctrl() and sci_shutdown() are called in this order.

No, I haven't tried GPIO RTS/CTS so far. How would this be configured?
