The Ethernet LED illuminates if the Ethernet port is connected and blinks when data is transmitted or
received.

SERIAL LED

The serial port has an associated LED. The Serial Port LED blinks (green) when data is being
transmitted or received on the serial port. When the LED is On, it indicates that the serial port is open.
