Developer’s Description

By Ingenieurbuero Paule
Enable direct hardware access for existing software without programming.

Direct I/O is the world's first device driver for Microsoft Windows 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. There is no need to update to 32bit versions any more. Version 4.4.271 has fixed driver start behavior when running on machines with PAE extensions enabled. Changed display of network path loggings in the event log from error to warning (which are not stored at all under default settings).
