Method for controlling activity indicators of an electronic appliance

Abstract

A method for controlling activity indicators (161-164) for indicating activity of interface drivers (230-250) of an electronic appliance, wherein the electronic appliance comprises a memory (114) with a file system (210), wherein each interface driver (230-250) has associated a corresponding directory in the file system (210) for storing files representative of an activity of the interface driver (230-250), the method comprising periodically performing a background process (270) comprising: calculating (414) a current message digest for the file corresponding to the interface driver (230-250) activity; comparing (416) the message digest with the last stored message digest; upon detecting a change of the message digest (419, 422), generating (420, 423) a state message for the activity indicator (161-164) corresponding to the interface driver (230-250); sending the state message the activity indicator (161-164).
