  // this serial code contains small portions of the following code-examples:
  // ---------------------------------------------------
  // http://todbot.com/arduino/host/arduino-serial/arduino-serial.c
  // web.mac.com/miked13/iWeb/Arduino/Serial%20Write_files/main.cpp
  // www.racer.nl/docs/libraries/qlib/qserial.htm
  // ---------------------------------------------------
  
  // notes:
  // ----------------------------
  // when calling setup("....") you need to pass in
  // the name of the com port the device is attached to
  // for example, on a mac, it might look like:
  //
  //                 setup("/dev/tty.usbserial-3B1", 9600)
  //
  // and on a pc, it might look like:
  //
  //                 setup("COM4", 9600)
  //
  // if you are using an arduino board, for example,
  // you should check what ports you device is on in the
  // arduino program
  
  // to do:
  // ----------------------------
  // a)         support blocking / non-blocking
  // b)         support numChars available type functions
  // c)   can we reduce the number of includes here?
