A system adds functionality to a power button where use of the power button controls the entry and exit from a diagnostic mode. The system includes an information appliance connected to a diagnostic appliance. Once an information appliance is powered up, the information appliance monitors its power button for a press which indicates a request to enter a diagnostic mode. Absent a press of the power button, the system continues to be under control of the information appliance and never enters a diagnostic mode. However, if a press of the power button is detected, the system enters a diagnostic mode. Once in a diagnostic mode the system provides an exit therefrom by interpreting a power button press as a request to exit. The window of time to make such an exit closes once the diagnostic appliance achieves communication with the information appliance. If the power button is pressed during this window of time, then the system ends its diagnostic mode and control of the system returns to the information appliance. If the power button is pressed after the window of time has closed, then the diagnostic appliance retains control of the information appliance and maintains its ability to execute diagnostic type commands thereon. The illustrative system is particularly useful when incorporated into devices with limited interface connections such as legacy-free information appliances. The system allows for a standard existing button on the information appliance to serve diagnostic purposes, avoiding the need for initializing peripherals requiring substantial execution space.
A method of using a power button of an information appliance to control entry into a diagnostic mode, wherein the information appliance is already powered up at system startup by an initial press of the power button, comprising the steps of:
A method of using a power button of an information appliance to control execution in a diagnostic mode, wherein the information appliance is already in a diagnostic mode after the detection of a first subsequent press of the power button, comprising the steps of:
A method of using a power button of an information appliance to control execution in a diagnostic mode of the information appliance, wherein the information appliance is already in a diagnostic mode after the detection of a first subsequent press of the power button, comprising the steps of:
An information appliance adapted for a power button to control entry into a diagnostic mode, wherein the information appliance is already powered up by an initial press of the power button, comprising:
An information appliance adapted for a power button to control execution in a diagnostic mode, wherein the information appliance is already in a diagnostic mode after the detection of a first subsequent press of the power button, comprising:
An information appliance adapted for a power button to control execution in a diagnostic mode of the information appliance, wherein the information appliance is already in a diagnostic mode after the detection of a first subsequent press of the power button, comprising:
A processor readable medium, capable of being read by an information appliance, wherein the information appliance includes a power button and the information appliance is already powered up at system startup by an initial press of the power button, the processor readable medium comprising:
A processor readable medium, capable of being read by an information appliance, wherein the information appliance includes a power button and the information appliance is already in a diagnostic mode after the detection of a first subsequent press of the power button, the processor readable medium comprising:
A processor readable medium, capable of being read by an information appliance, wherein the information appliance includes a power button and the information appliance is already in a diagnostic mode after the detection of a first subsequent press of the power button, the processor readable medium, comprising:
An information appliance adapted for a power button to control entry into a diagnostic mode, wherein the information appliance is already powered up by an initial press of the power button, comprising:
An information appliance adapted for an information appliance power button to control the execution of a diagnostic mode, wherein the information appliance is already in a diagnostic mode after the detection of a first subsequent press of the power button, the information appliance comprising:
An information appliance adapted for an information appliance power button to control the execution of a diagnostic mode, wherein the information appliance is already in a diagnostic mode after the detection of a first subsequent press of the power button, the information appliance comprising:
