I have a desire to control the WMF 1200s from my computer.
I installed the WMF 1200s service program - where I could connect to the coffee machine via the USB (COM port).
In the test functions you can control the components of the coffee machine - start the rinse, connect the light buttons, start the grinders and so on. But when you run a command to activate the buttons - the program displays an error with the connection to the COM port (TIMEOUT COM PORT)/

Maybe it's in the version of the service program - and in some of the buttons can be controlled via a test mode (like how it is implemented in konfigTool for 2000s).

Or does anyone know how to send commands from the PC via USB to call commands to the Buttons.
