Abstract
Storing a variety of appliance control codes in a cordless digital telephone handset has the advantage that the cordless digital telephone handset can be used as a universal remote for a variety of electrical appliances. The cordless digital telephone handset need not be in the direct "line-of-sight" of the appliances in order to work. The appliance control data can be sent along with voice data in a method such as digital spread spectrum communications.
