// 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
