Abstract: A method for data communication between a multiplicity of devices coupled to a LAN Bus without data transmission collisions. Each device is assigned a unique device address and a unique transmit time slot based thereon. The method involves responding to each data character received in each receiving device by loading a LAN.TIMESTAMP parameter with the CUR.SYS.TIME parameter. Thus the LAN.TIMESTAMP parameter indicates the time of the last data character when an incoming data packet terminates. Packet termination is declared when the LAN Bus is quiescent for a period after the last character equal to the PKT.END.DELAY value which is preselected. The method also involves determining whether the value of CUR.SYS.TIME represents a point in the unique transmit time slot for the device and then in response to determining that CUR.SYS.TIME is within the time slot, initiating the transmission of data if available, or otherwise, setting a new LAN.TIMESTAMP value.
