Marcel Moolenaar f1fb96475a In uart_tty_outwakeup(), check CTS/RTS flow control settings and
prevent sending data when CTS is de-asserted.
In uart_tty_intr(), call uart_tty_outwakeup() when the CTS signal
changed, knowing that uart_tty_outwakeup() will do the right
thing for flow control. This avoids redundant conditionals.
