I've noticed that AIDA64 writes data to random serial ports when 'Low-level SMBus operations' is checked in the Preferences > Stability tab
the data sent always seems to be the bytes "0, 224, 0, 255"
This is a problem because i have been tinkering with a platform called Arduino which uses a serial port to update the 'sketch'. 80% of the time when i try and update the sketch i will get the error "Serial port 'COM3' already in use. Try quiting any programs that may be using it.". However when i disable 'Low-level SMBus operations' it works 100% of the time
of course disabling 'Low-level SMBus operations' isnt really and option as it disables all of the sensor information.
