+// 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.
