BBN support for MacArthur HAT

[GerryB]

I have now managed to get BBN running smoothly on my RPi 5 fitted with a nVME SSD card, USB GPS receiver, o-charts and an RS-422 dongle feeding in AIS data, thank you.

I have a MacArthur HAT which I'd like to connect, however I don't see how to enable the required UARTs as there does not appear to be a Serial application in the package. Am I missing something here, or is there another way to get the HAT recognised?
Thanks, 
G
