Once or twice a year somebody mentions porting cncpro over to windows. Having
looked at the source code I am convinced this would be very difficult. Here is
some help for anyone willing to try.

Hadcon RTM is a real time driver for W2K/XP that runs in ring 0. The author
developed it specifically for applications such as cnc. This driver is available
under GPOL and includes source code. You can get it at codeproject if you are a
member:

It is also available from other sites, though I think codeproject has the latest
version. You will note the usual bashing in the feedback section of the above
URL. Take note that all such comments ignore the intended scope of the project.

If I had the programming cajones to tackle such a project, however, I would
convert emc2 rather than cncpro. Emc2 has more potential because it is
documented and the CV function actually works.
