Inter-Duplication Interface Circuit Pack Loop
Back Test (#280)
This test loops back data through the UART used to communicate with the other
Duplication Interface circuit pack. The data is generated by the Duplication
Interface circuit pack processor and is looped through the UART. The test is done
entirely on the Duplication Interface circuit pack. The test passes if the data sent
matches the data received. This test does not check the physical serial channel
that is printed on the backplane or carried by the ICC.
