  • Method and apparatus for communication variable length messages between register modeled radio devices
    Patent number: 5551068
    Abstract: A radio system (100) includes a plurality of addressable processors (150, 180, and 200). A communication link (230) interconnects the addressable processors (150, 180, and 200). The communication between the addressable processors is conducted via a first and a second communication protocols. The first communication protocol includes a plurality of fixed length information packets for passing parametric data to or from the addressable processors at a fixed baud rate including a packet for changing the communication protocol. The second communication protocol includes a plurality of variable length information packets for passing parametric data to or from the addressable processors at selectable speeds. Whereby the operating state of the addressable processors may be determined or altered by, respectively, communicating parametric data from or to the addressable processor at variable baud rates.
