ABSTRACT:
A plurality of terminals are connected to a common data bus. Each terminal is capable of issuing and processing two types of commands: a simultaneous command and a non-simultaneous command. A receiving terminal processes every simultaneous command, but processes only the most recently received non-simultaneous command. The receiving terminal acknowledges the receipt of every received simultaneous command and of every executed non-simultaneous command. The receiving terminal sends a reject signal for every received non-simultaneous signal that was not executed.
