max232 draws a lot together with the mouse it could be too much. But currently it is not my problem. The problem is, that RTS is at -12V and toggles very shortly to +12V and back to -12V in that period I have to initialize the MCU and finalize serial initialization to get the mouse driver to eventually flip the voltage back to 12V again. It's a bit more complicated, than looks like at the first glance. I don't want to tell anything wrong now, but I'm in it and will report as soon as I got more info.
