A method for handling upgrades of systems comprising two circuit packs which contain memory. In one embodiment, on some trigger signal to a circuit pack, that circuit pack acts as a slave circuit pack, and causes version information for the data stored in the memory of the second circuit pack, which acts as a master circuit pack, to be transferred to the slave circuit pack. If the transferred version information indicates that the data in the slave circuit pack should be updated, the slave circuit pack causes a transfer of information from memory in the master circuit pack to the slave circuit pack, and stores the new information in the memory of the slave circuit pack.
A method and system for automatically updating the revision level of programmable devices is disclosed. In one aspect, the system may comprise a master programmable device having pulse receiving logic and memory, and one or more slave programmable devices having pulse generating logic. The slave devices may be coupled to the master device through an interface and configured to automatically send revision information to the master device responsive to the revision information being generated in a slave device.
A portable electronic device is disclosed that is reprogrammable through a pager network. The device includes a communications port. The device also includes a data transceiver for transmitting send data and receiving receive data from a pager network. In addition, the device has a processor. The processor is in electronic communication with the communications port for communicating through the communications port. The processor is also in electronic communication with the data transceiver for communications with the pager network. The device also includes reprogrammable memory programmed with instructions to cause the device to receive new program code from the pager network and to reprogram the reprogrammable memory with the new program code.
