Review on StarTech.com Native PCI Express Combo Card: 2x Serial 1x Parallel RS232 Adapter (PEX2S5531P) by Jim Worthington

Installed on Windows 10 with Intel Desktop Board LGA1155 DDR3 1600 ATX - BOXDZ77GA-70K. At first I couldn't get it to work, but after reading the reviews I found a reviewer who went to the Startech website and downloaded the drivers from there. You should also reboot when you see the assigned COM ports. Also make sure that the parallel port cable is installed with the red line opposite as shown in the picture. I haven't used ports yet, but will soon.
