RS-232 LED link Tester DB-9 Male to DB-9 Female

Product Review (submitted on June 8, 2020):
I have a 25-pin version I've used for years, with gender-benders and adapters. It's much easier to use a 9-pin monitor. This one is easy to use, lightweight, and easy to read.It's great for us dinosaurs that still use RS-232 instead of USB, or with a USB-to-RS-232 cable.
