ABSTRACT:
A data bus and message handling method provide a definitive means of indicating a client-aborted message for data bus systems which employ a message protocol that requires each message conveyed between a client device and an originating device to automatically and atomically include a frame check sequence (FCS). When a message is not to be client-aborted, a ‘good’ FCS is generated by a first method, typically based on the message's data content. However, when a message is to be client-aborted, the FCS is generated by a second method which requires modifying the good FCS value to create a ‘bad’ FCS, preferably using a mathematical means that preserves the uniqueness of the bad FCS to a high degree.
