Firmware updates Whenever the on-board software must be upgraded or modified, the new firmware can be downloaded to the internal flash memory via the radio clock's serial port COM0. There is no need to open the computer case and insert a new EPROM. If the button behind a hole in the rear slot cover is pressed twice, a bootstrap loader is activated and waits for instructions from the serial port COM0. -
