Abstract: A method and apparatus is provided for automatically determining the asynchronous serial data communication characteristics of a transmitting device and automatically configuring a receiving device with these characteristics. The method of determining the data communication characteristics can be initiated on demand with the results of the determination stored in non-volatile memory for continual, repetitive use by the receiving device.
Abstract: An alarm system includes a floating transmitter which when activated by a wave will generate one short signal and then turn itself off. A radio receiver will detect and verify the time duration of the radio signal, and thereupon activate an audible alarm. The alarm will continue to sound until it is manually turned off.
