摘要： An encryption key interface system (200) includes a universal asynchronous receiver transmitter (UART) peripheral (209) that communicates with a key variable loader (KVL) (201) through a communications link (205, 207). A driver application (211) associated with the UART peripheral (209) is used to both receive and transmit commands to the KVL (201). The invention operates to allow the driver application (211) to communicate key command information to the KVL (201) without the use of a timer peripheral enabling the system to interface with a much broader range of devices utilizing encryption keys without requiring the use of timer system resources.

摘要： A method for call setup in an asynchronous frequency hopping digital two-way communication system includes transmitting in adjacent time slots, by a caller device, a preamble slot over a first unique fixed frequency selected from a frequency hopset and a synchronization slot over a second unique fixed frequency selected from the frequency hopset. Further, the method includes one or more target devices transmitting an acknowledgement signal upon receiving the preamble slot over the first unique fixed frequency and the synchronization slot over the second unique fixed frequency, and followed by the caller device establishing the data communication link between the caller device and the one or more target devices over at least one random frequency selected from the frequency hopset, in response to receiving the acknowledgement signal from the one or more target devices.
