Firmata Serial protocol device emulator

/*
 * Emulate a simple serial device in order to test the Firmata Serial protocol.
 * Connect the rxPin to the TX pin of the configured port of the board running StandardFirmata
 * Connect the txPin to the RX pin of the configured port of the board running StandardFirmata
 * 
 * Use Serial to read and write to the board running StandardFirmata
 * Use SoftwareSerial to write data to a console to test SERIAL_WRITE
