Read COM port serial transmission
#1
Hello.
I'm trying to make a system to control the backlight of my monitor. I have managed to control the backlight through ‎DDC/CI.

I need a way to read the information sent from a light sensor board via COM port in order to automate the process.
I need to read only a number.

Thank you
