// Instructions For Use:
// Define the manifest constant USE_FTDI if you want to use a separate FTDI module to issue commands on
//   which frees the Serial output for normal debugging output
// 
// You can use just the Serial port by itself to issue commands and retreive the output
// but then you cannot use the Serial Monitor window for debugging.

// Un-comment to use an FTDI port for commands and the Serial port for debugging output
//#define  USE_FTDI
