Direct I / O is the world's first device driver for Microsoft Windows NT, Windows 2000 and Windows XP which enables the direct hardware access for your existing software without any programming efforts on your side.

It is especially useful for existing 16bit software which accesses special hardware, e.g. programmers or data acquisition boards.

Even 32bit software developed by you benefits from the easy access to the hardware. You'll never have to bother with complex and expensive DDK toolkits again.

With Direct I / O you can continue to use your existing software and hardware after migrating to Windows NT, Windows 2000 or Windows XP. There is no need to update to 32bit versions any more.

Keep your investments!
