Abstract
A pen-based computer system device includes a digitizer and utilizes a passive stylus as an input device. The system emulates standard two-button mouse functions by generating data packets corresponding to the x-y coordinates of the stylus for each pen-down event. In order to prevent malfunction of the system, a plurality of packets are generated for each pen-up event to prevent maloperation of the system in the event a data packet for a pen-up event is lost or garbled.
