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- 1 2A 2B 3
The item will either be 'OK' or 'FAIL' to indicate an overall condition.
The items are phase specific to indicate which phase is failing.
The 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
