ABSTRACT:
A remote control unit responds to activation of a "identify" button by transmitting a sequence of command signals, each of the same command in a different format. Since the appliance to be controlled is turned on, it responds in a predetermined way (e.g. a channel change) when it receives the properly formatted command. The user then terminates the learn mode and a pointer denoting the address of the last transmitted command, i.e. the properly formatted command, is stored in the unit and used as part of the address for reading data for subsequent user-selected commands out of memory.
