ABSTRACT:
Updated operating code and parameters can be reprogrammed into a modem system with no disassembly of the modem hardware. The modem system includes an in-circuit reprogrammable memory chip in which operating code and parameters are stored. Two control programs control the reprogramming of updated operating code. One of the control programs is designed for manufacturing and testing purposes. The other control program allows remote reprogramming of updated operating code or parameters from a remote location such as a customer site. The modem system is portable, obtaining power from a standard 9 volt battery. Therefor, various power saving features are also incorporated into the modem system.
