@Verkehrsrot First I would like to express my apreciation for the work in PAXCounter. It is a huge job to keep it maintained and receive and react on all responces from users. From experience I know what it takes. I feel sorry for always only pointing on things that are not as opimized as one would like. Therefore this intermezzo; Thank you. I hope we can continue to work on and with PAXcounter.
With respect to the logic on screen saver: I can think of a timed state that, when screen saver is enabled, will switch of the display after a preset time and switch it on, on events like a keypress or when data is sent. So the display state kan be: ON, SCREEN_SAVE, or OFF.
It might be possible to use the same variable for display on and off and add a third value for screensave:
0=off, 1=on, >1 is screensaver timeout in seconds.
Although I hve not fully examined the code, this seems initially an implementable solution.
