F. UMD UPDATE STYLE CHANGE
This command sets the update style for the UMD and applies to
firmware versions 2.x or later. This command allows you to
choose between two styles of update. One mode is an
instantaneous update where the updated data will instantly
replace the original data without blinking. The other style
is a “blink mode.” When data is sent to the UMD, the UMD
will momentarily blink off and then on again with the new
data. The format of this command is:
<IDnn><Bx> cr lf
where x = 0 (zero) for an instantaneous (no-blink) update, or
where x = 1 for the blink mode update
