Simply plug these adapters onto the end of a cable and you're done ! The low profile design reduces leverage strain on overstressed computer ports and is fully shielded for electrically noisy environments.

Review: This solved my big problem. - Perfect connector and convertor from straight to cross null modem.
Review: Works perfectly ... - These null modem adapters worked perfectly for me. I used them to put two USB RS232 adapters together back-to-back for testing purposes. My only wish was that both sides of these adapters had female screw posts to allow my RS232 adapters to both screw into these null modem adapters. They are perfect for me otherwise.

RS232 is still around but it is difficult to find support cable products. These adapters fill the bill and work great at a reasonable price.
