Serial Port Loop-Back Test

You can use the serial port loop-back test to test your serial hardware configuration. This test can be used with any COM port, whether it is local, or on a multi-port serial board (such as a DigiboardA high-speed serial board manufactured by the Digiboard Corporation.). The test can be performed internally or externally with loop-back cable attached.
