"Safety at Work" monitor diagnostics
Function: 0x02
As the "Safety at Work" monitor can produce more than 32 bytes of
diagnostics data, this must be read with several mailbox calls. In doing so, the
second request byte specifies the start index in the diagnostics data field.
When the start index = 0, new data are fetched from the monitor, otherwise the
function responds from the store, as a result of which the data can be read
consistently.
