ABSTRACT:
A novel method is disclosed that facilitates secured transmission of data between the transmitting and receiving ends of a cordless telephone by encapsulating the desired command in a message code. This message code includes synchronization, security, and error detection codes as well as the encapsulated command. Both the process that generates the security code and the process that enables recovery from errors during data transmission efficiently utilize the limited memory and processing capabilities available on the cordless telephones.
