SUMMARY
Some MS-DOS-based applications require that you plug hardware keys into an LPT port for copy-protection purposes. These hardware keys (sometimes called "dongles") are not supported with Windows NT.
MORE INFORMATION
Hardware keys usually require a device driver that has direct access to hardware. Software vendors who use hardware keys need to write a special MS-DOS-based device driver and a virtual device driver (VDD) to allow their applications to run with Windows NT.
The following products require such drivers:
- Micro Focus COBOL uses a hardware key and does not have device drivers available at this time to support Windows NT.
- Tango Schematic
- Tango PCB (printed circuit board)
- Tango Route
- Clarity fails under Windows NT 3.51 because it cannot locate the hardware key.
The listed products are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding their performance or reliability.
