ABSTRACT:
A method for using an operating system device for non-operating system uses. A false event signal is generated to indicate that a device should be shut down. After this is accomplished, the device is used for a different purpose while the operating system thinks it is inoperative. Once the other use is completed, another false event signal is generated so that the device is activated again and returned to use in the operating system in normal fashion.
