  // of use.  For example, a GPS module would normally connect to SERIAL_PORT_HARDWARE_OPEN,
  // the first hardware serial port whose RX/TX pins are not dedicated to another use.
  //
  // SERIAL_PORT_MONITOR        Port which normally prints to the Arduino Serial Monitor
  //
  // SERIAL_PORT_USBVIRTUAL     Port which is USB virtual serial
  //
  // SERIAL_PORT_LINUXBRIDGE    Port which connects to a Linux system via Bridge library
  //
  // SERIAL_PORT_HARDWARE       Hardware serial port, physical RX & TX pins.
  //
  // SERIAL_PORT_HARDWARE_OPEN  Hardware serial ports which are open for use.  Their RX & TX
  //                            pins are NOT connected to anything by default.
