My ASrock 990FX Extreme 4 motherboard came with a 9 pin serial header. I have a radio programmed with a serial cable and this adapter allows me to move code plugs back and forth with my windows 8.1 installation. It basically does what it's supposed to and I haven't had any problems. I will note for those interested in aesthetics that if you tape off the connector and 9-pin connector you can plaster the whole assembly with plastid to match if you have a darker setup like mine. Plasidip works great with cables (especially ribbon cables as they are flexible).
