I use this on Arduino projects to detect which lines have the data on them. I wish I had bought one of these years ago.
Quality Value Price - 9 Pin Serial "Tester" - RS-232 LED link Tester DB-9 Male to DB-9 Female

Good for "seeing" your serial traffic and connectivity. Small and compact. Well built. LEDs light up when the pins are active and flash when traffic is passing.

Works very well, glad to have it. The female-thread retainers were cumbersome and interfered with some cables; I had to remove them with pliers. Also would have preferred lights to shine red for positive, green for negative, but it's ok this way too. Very handy item.

The light for each line shows either none (dim), green, or red. I am not sure whether green means high, and red low, or something else. It works very well for loopback tests (TX connected to RX). It can only be inserted between two cables, not between a cable and a chassis.
Quality Value Price - Great little lamp box.

I first used this device when I was commissioning data centers for Clearwire. Our job was to start up a newly built data center. Most network equipment is initially configured via a serial connection. Most adhere to the "Cisco standard" but some are just down right odd. One of our tasks was to connect each device to a terminal server. That meant that we had to figure out each pin-out. This little matchbox sized lamp box saved our arses. If your life involves connecting to various odd serial ports, you want this. If you have a serial cable in your kit, you want this in there with it.
Quality Value Price - Excellent tester.

Though devices using serial connectivity are becoming a thing of the past, there are still a good number of devices that are not available with native USB connectivity and require serial port connectivity. Unfortunately, serial devices are not as plug-and-play as USB devices and thus often require some level of troubleshooting to get them up and working. This handy little link tester can be invaluable in determining if the serial connection is mated properly and if communications is occurring. I have used a number of these types of devices over the years and this particular 9-pin device is very convenient. The only drawback is the LEDs are not as bright as I would like to see. If you are in a brightly lit room or out of doors, it may be difficult to see the indication. Overall, I give this tester a thumbs-up.
