6.1.7 Status Reply*
This command will be sent by the Radio to the OEM Host in response to a Status Request
command. All the different parameters pertain to the data link layer and are cumulative totals. Once this
command has been sent back to the OEM Product, depending on whether the OEM Product desired an error
counter variable reset, the reset operation is carried out. The different statistics and their sizes are shown
below:
