-/* 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
