Using the UART2 ports PcDuino 3 nano

Greetings -
 

I'm trying to use the UART2 port (Connector J11 pins 1 and 2) and I'm not having much luck with Armbian 5.0 Vanilla. There are /dev/ttyS0-7 listed, but I get nothing from them (save ttyS0 which is the main console and in use by getty). I found several other articles in here talking about how to expose the GPIO pins, but I could not see how to set the "mode" of them. Any assistance would be appreciated!
