From b095cd5077a345de1f0b52be7357745cc0b472ad Mon Sep 17 00:00:00 2001

Subject: set num_other_fields to zero. send an ack to a current rev client. if
 changing or setting exposure, also update the time. location needs to be sent
 back to the sender. found is still a pointer, not an int (yet another bug)
 return an answer, not garbage
