It shows up as a couple of COM ports under Windows server 2003, and works very well indeed.StarTech's definitely got a winner with this one. If you have need for RS485 ports, it won't get much better than this. ### ⭐⭐⭐⭐ Four Stars *by B***N on Reviewed in the United States on March 16, 2014* Ok ### ⭐ Doesn’t function reliably *by N***N on Reviewed in the United States on August 19, 2018* Driver set very weak.
