Clear Error Counters (#270)
This test is not an actual test in the strict sense of the word. Many circuit packs
have counters in the Angel firmware. These counters are used so that CCMS
(Control Channel Message Set) messages are not continuously sent uplink.
Using this method, the message are sent once, when the counter reaches some
preset threshold, and then not sent again until the counter is cleared.
The ports on the Maintenance/Test circuit pack continually run self-tests,
whenever the port is idle. The Angel uses a counter so that the Background
Maintenance Failure message is only sent uplink once (this keeps a failed
port/circuit pack from flooding the SPE with a string of messages). This test is
used to clear the counter, so that if the port continues to fail during or after
SPE-demanded testing, the Angel sends a message to indicate that fact.
This test is only used to send a message to the Angel on the Maintenance/Test
circuit pack. Therefore, this test should never abort or fail.
