Task Priority
A task is responsible for monitoring each serial port for messages. The real time operating
system (RTOS) schedules the tasks with the application program tasks according to the task
priority. The priority can be changed only with the set_protocol function from an application
program.
The default task priority is 3. Changing the priority is not recommended.
