Conceptual design
The MCB Software layer is constructed as a VxWorks task. The task
accepts requests from clients to interact with the SIBs on the bus
through some IPC mechanism, such as a pipe, socket, or queue, and
handles all the details, such as prioritizing, figuring out which
serial port the SIB is connected to, checking the status of each
operation, and returning the results to the requestor.
