Phase Query (NEW)
This function queries the current state of the phase detection system. Phase zero-crossing detection occurs at
all times.
 In the presence of a phase/zero-cross error, the AxLink LED will blink very fast (more than 10Hz)
and all string responses with strings that give responses will be "PHASE ERROR!".
 The response will be an incoming COMMAND to the master.
Phase Query
Command: ?Y
Response: Y-<pass/fail> 1<state1> 2A<state2A> 2B<state2B> 3<state3>
The <pass/fail> item will either be 'OK' or 'FAIL' to indicate an overall condition.
The <state> items are phase specific to indicate which phase is failing.
The <state> will either be 'Y' for okay or 'N' failure.
Examples: SEND_COMMAND Radia,'?Y' check phase status
Response: 'Y-OK 1Y 2AN 2BN 3N' Good response
SEND_COMMAND Radia,'?Y' check phase status
Response: 'Y-FAIL 1Y 2AN 2BN 3Y' Fail on 2A and 2B
