Abstract
The invention concerns a stylus for use with a digitizing tablet, such as that associated with the display of a portable computer. The stylus contains memory which stores data such as operating state (i.e., states of user-controlled buttons, state of charge of battery), a stylus identification code, and fault codes, which indicate error conditions which arise. The invention transmits the contents of memory, by a serial bit stream, to the computer.
