-  On the Arduino DUE (version 1.6.8) using the Serial port pins as digital IO
-  pins is problematic. In particular, it seems you cannot use the port as a
-  serial port after using pinMode() on the pins.
-
-  We fix this by using an extra pin; we use this extra pin to create the slow
-  5 baud init pattern while the Serial pins remain in use for the serial port.
-
-  So connect any digital pin to the Tx pin of the serial port and update the 
-  number accordingly.

#define RX_PIN 19

// An extra pin connected to the Tx pin of the Serial port used. 
#define TX_PIN 18
// So this pin has a direct connection to pin 18 (TX1)

// The ENable pin for my SN65HVDA195 breakout is connected to pin 2.
