    I'd rather verify_port didn't get used for that - it's purpose is to
    validate changes the admin makes to the port.

    I don't know why you think that setting 9bit mode should be done this
    way rather than through the usual termios methods - the termios methods
    already have a way to control the length of each character, so it would
    seem logical to put the control in there.
