Prolific (PL2303) drivers for Windows

Most Byonics products will work with the latest Windows drivers provided by Microsoft. If you have trouble with a blue BFoxCon USB-TTL cable, or if you see the text "THIS IS NOT PROLIFIC PL2303. PLEASE CONTACT YOUR SUPPLIER." then we recommend trying the older version of the PL2303 drivers with the instructions below.
