Wanting to add a serial port expansion slot adapter to the GA-H81TN super-tiny ITX board. All the serial ports i'm finding online are DB-9 to IDC-10 (like this http://www.startech.com/Cables/Serial-Parallel-PS-2/DB9-DB25/9-pin-Serial-to-10-pin-Header-Slot-Plate-16-inches~PLATE9M16 ), but the port on the Gigabyte board doesn't visually look like that. Any ideas what it is?
