Abstract
A device driver in a computer system being controlled by an application program has selectable algorithms for making desired changes to the signals produced by an external device. The signal changes are in addition to any changes which are needed for conforming the external device signals into a data structure required by the application. Selectable algorithms include a data filtering capability as well as a procedure to enhance the data produced by the external device.
