<p>A method and apparatus for communication synchronous and asynchronous data among multiple devices which are connected by a common network. If synchronous data signals must be communicated between two or more devices the transmitting device sends asynchronous data signals to the receiving device(s) to indicate that synchronous data will follow, and to inform the receiving device(s) of the transmitting device's address. The receiving device(s) sets up a message filter (33) which looks for and accepts data packets bearing a destination address field value equal to the address of the transmitting device. The transmitting device converts the synchronous data into one or more data packets bearing destination address field value equal to the transmitting device's own address, and transmits the data packets over the network. The receiving device receives the data packets and reassembles them back into a synchronous data signal. Thus, the transmitting device needs to send the data packets only one time, rather than sending duplicate data packets to several receiving devices.</p> |
