I can't get Serial1 to work, and in my digging, I note that TX is connected to GPIO18 and RX is connected to GPIO19. However, in the Serial example, the table doesn't show that as a viable pair. Only 18,15 and 20,19 seem to be close... At this point I'm working down the path of undefining Serial1 (in the bowels of Arduino) and picking a different pair. Thoughts?
