Statistics (16H)
The RF3880 adapter keeps track of several types of board statistics. With the
Extended Board Statistics command you can retrieve the extended set of
statistics kept by the adapter. The statistics are valid only as long as power is
kept to the system. This command reports the statistics by recording them in
the area of system memory specified in the command Parameter Block; this
statistics structure is returned in addition to the normal Status Block.
