Requesting VESC fault codes via UART

I'm currently using the UART to continuously show me my speed, battery remaining, amps drawn...  I do this via bluetooth and display it on an LCD display on my remote.  I also log the values that are returned from a COMM_GET_VALUES command.  My question is this... How can I capture fault codes?  I see there's an "mc_fault_code fault_code;" in the mc_values struct.  Does that mean it will return the most recent fault code?  What if there are multiple faults?  Do I have to clear a fault in order to see the next one in the list?

Thanks very much for any tips.
