Perform A Serial Loopback Test; Mount The Serial Hub In A Server Rack - StarTech.com ICUSB23208FD Manual

Perform a serial loopback test

To verify that a port is operational and to map the ports, you should perform a serial
loopback test. A loopback test sends and receives data to and from the same serial
port. To complete the loopback test, you need to temporarily connect pin two and pin
three to allow the signals to be sent and received on the same port.
To perform a serial loopback test, you need a loopback adapter and a third-party
software program (for example, PuTTY or HyperTerminal®).
1. Download a third-party software program.
2. Open a connection on the COM port that you want to test.
3. Insert the loopback adapter into a serial port.
4. Type something in the third-party software.
If what you typed is displayed in the window, you have located the correct port. If the
text isn't displayed in the window, move the adapter to another port and try again until
you find the correct port.
