#ifdef __cplusplus
// These serial port names are intended to allow libraries and architecture-neutral
// sketches to automatically default to the correct port name for a particular type
// 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.
