ABSTRACT:
A method of controlling communication for a communication system for connecting a plurality of electronic apparatuses through a communication control bus and allowing data communication between those electronic apparatuses wherein each of the electronic apparatuses performs connection control through the execution of a connection control command carried out by writing connection control information in a predetermined storage memory of its own or another electronic apparatus. The electronic apparatuses which attempt to write the connection control information transmit the write instructions to a predetermined storage memory. The storage memory which has received the write instructions, in turn executes only the earliest write instruction received and then transmits responses indicating whether the execution of the respective write instructions was successful or not.
