Thanks, TTYL The device driver component, which as far as I can tell is only used in the NT/2000 case, requires Microsoft's DDK and would probably be difficult to build with any compiler other than VC. The DLL component could probably be relatively easily built using BC Builder. In fact, the code that is in the DLL could even just be included directly into a BC Builder project (probably with some minor modifications), eliminating the need for a separate DLL.
