The Serial Port Test is a loopback test that checks whether data is being correctly transmitted and received on any port. The test also checks, using DTR/CTS/RI or RTS/DCD, whether the box can loop back control leads correctly. To use this test, you will need to jumper Pins 2 and 3. To test DTR/CTS/RI and RTS/DCD, you’ll need to jumper Pins 20, 5, and 22 together, and jumper Pins 4 and 8 together.
