Recovering from Holdover _________________________________
This query returns prioritized reason for why the Receiver is waiting to
recover.
Response
HARD indicates there is an internal hardware reason, GPS indicates there are
no satellites, LIM indicates the time interval between GPS and internal
oscillator is exceeding the limit, and NONE indicates the Receiver isn’t waiting
to recover.
Note that if holdover has been initiated by sending the :SYNC:HOLD:INIT
command, the Receiver is not waiting to recover; the response is NONE.
This query is always valid. If not in holdover and waiting to recover, NONE will
be the response.
This command initiates a recovery from manually initiated holdover. Use this
command to take the Receiver out of a manually selected holdover. This
command is not needed to initiate holdover recovery in any other situation.
