     that would be quite an unusual set up. The product overview for the 
GL128 has some differences with the GL123 and GL125. Guessing the usage 
of registers will complicate the task.
     If the scanner can be switched off remotely to reset it, or to 
avoid stressing it when backend doesn't behave correctly, I'll have a 
try working on it.
