1. A cordless telephone system comprised of:
a cellular telephone adapter providing operative interconnection with a cellular telephone having a communications port, the
adapter comprising:
a base interface connector capable of conveying a plurality of electrical signals;
a cellular telephone interface connector configured to engage with the communications port of the cellular telephone, which
cellular telephone interface connector is also operatively linked with the base interface connector providing for the conveyance
of electrical signals between the cellular telephone interface connector and the base interface connector;
an adapter digital memory device electrically interconnected with the base interface connector, the adapter digital memory
device containing driver-core interface code and driver code;
a base unit comprised of:
an adapter interface connector configured to electrically engage with the base interface connector;
a base unit digital memory having core application code, core-driver interface code, a storage region for driver-core interface
code, and a storage region for driver code, the core-driver interface code and the driver-core interface region each being
located at predetermined positions within the base unit digital memory;
a microprocessor operatively connected to the adapter interface connector and the base unit digital memory, the microprocessor
being configured to read the driver-core interface code from the adapter digital memory device and to store the driver-core
interface code within the driver-core interface region of the base unit digital memory; the microprocessor being further configured
to read the driver code from the adapter digital memory device and to store the driver code within the driver code region
of the base unit digital memory.
