How do I test a serial port?

To test if the computer COM port is functioning correctly, you can do a simple loopback test. (In a loopback test, a signal is sent from a device and returned, or looped back, to the device.) For this test, connect a serial cable to the COM port that you want to test. Then short pin 2 and pin 3 of the cable together.
