Hunt for burst pulse (BPHUNT)

The BPHUNT command allows the host computer to initiate hunt mode when it knows or can sense that a burst pulse should be present.

BPHUNT starts the internal procedure to hunt for a missing burst pulse when we are uncertain of both its time and frequency.

Depending on how the hunting process has been configured in the Mb menu, the procedure may take several seconds to complete. The RVP10 host computer interface remains functional during this time, but any acquired data is questionable.

GPARM status bits in word #55 indicate when the hunt procedure is running, and whether it has completed successfully.

Now forces the hunt procedure to start even if the burst pulse is already present.

Normally the procedure only starts when the burst pulse is missing at the time BPHUNT is given.
