Regarding serial control signals:

Is there a documentation about the default serial control signals pin mapping? I.e. if I want to send CTS (clear to send) signal, what physical GPIO pin should I use?
Is it possible to map serial control signal to a specific GPIO pin?

I guess you should use default pins for serial: UART pins in BCM mode are: 14, 15

I am talking about the control signals. I think the answer is that I need to change the GPIO function to ALT3 or ALT5 to enable this functionality.
