In the RPi 3 you can switch the bt to the minuart with the pi3-miniuart-bt kernel dtoverlay. When you do this, the main uart is exposed on pins 8 and 10... and it maps to /dev/serial0. I guess my question is do we need to do anything to use this code to enable CTS / RTS on serial0 in this mode? Or does the remapping at the kernel level magically deal with this?
