Abstract:
A system for reprogramming a consumer electronic device includes a consumer electronic device (CED) having a CED processor and a CED memory and a CED serial port connected to the processor, the memory storing CED processor instructions and CED data. The system also includes a download module having a download processor and a download memory and a download serial port connected to the download processor. The CED processor periodically applies a signal to the CED serial port. When the download serial port is connected to the CED serial port to make a serial connection and the download processor receives one of the periodic signals from the CED processor, the download processor initiates the download of one or more of download instructions and download data from the download memory to the CED memory over the serial connection.
