Abstract
A method of allocating transmission time for a plurality of I/O devices (14) connected to a transmission line (12) comprising the steps of causing each device to listen constantly to determine if the line is being used and to only initiate a transmission after waiting a mandatory device delay period (31) and a reply slot period and thereafter to select a random number from 1 to N, with N being the number of bid slots following the mandatory time delay period and the reply slot period, and to begin transmitting only during the bid slot corresponding to the random number selected. Each receiving device is required to answer a transmission during the reply slot period to allow the transmitting device to ascertain that the transmission was received.
