Hi,
where is the need for this. Do you want to display
"Scanner needs xyz seconds for warming up?"
I think this may be nice but is not necessary for function
or do you want that the driver waits until the
scanner lamp is warmed up
there is no need to do this in the frontend.
The backend asks the scanner for warmup time
and does sleep() until the time is over
or does query the scanner until it answers
"lamp warmed up"
