Claim:
A method for supporting carrier sense multiple access/collision detection (CSMA/CD) on a home bus connecting a plurality of peripheral apparatuses, the method comprising: assigning priority to each peripheral apparatus and defining a different busy check time period for the peripheral apparatuses in accordance with the priority; if a peripheral apparatus has data to transmit, preparing the data for transmission by converting the data to a packet signal to be in correspondence to the home bus; if the home bus is in a busy state, waiting for a certain amount of time and rechecking the state of the home bus, and if the home bus is in an idle state, continuously checking the home bus during the defined busy check time period, to determine whether the home bus is in the idle state or whether the home bus changes to the busy state; and if the state of the home bus changes to the busy state during the defined busy check time period, waiting for a certain amount of time and then checking the state of the home bus again, and if the home bus is continuously in the idle state for the defined busy check time period, transmitting the packet signal.
