+/* YourDuino SoftwareSerialExample1Remote
+   - Used with YD_SoftwareSerialExampleRS485_1 on another Arduino
+   - Remote: Receive data, loop it back...
+   - Connect this unit Pins 10, 11, Gnd
+   - To other unit Pins 11,10, Gnd  (Cross over)
+   - Pin 3 used for RS485 direction control   
+   - Pin 13 LED blinks when data is received
