Checksum
The optional checksum must be enabled from the operating mode menu to
be available. The checksum is calculated by adding all the byte values (not
the ASCII translation values) in the packet (less the values in the header,
checksum if present, and terminator), discarding byte overflow and subtract
-
ing the byte sum from FFH.
Example ASCII Command
Fill Tag
This command fills the specified number of cells from the specified start ad
-
dress with the specified value. Block size = 0 means filling to the end of the
memory. The command will take the same form as the ABx Fast command.
