Chapter 7 Board-control Commands

Board Statistics (06H)
Board
Statistics (06H)
The RF3880 adapter keeps track of several types of board statistics. This
particular command maintains compatibility with earlier RF35XX products; it
is used to report three types of statistics. The Extended Board Statistics
command, described in a following section, reports additional board statistics.
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.)
You can clear the internal statistics table at any time by issuing the command
with the CLR bit of the Options field set. No data transfer occurs when the CLR
bit is set.
