Function to Continuasly monitor serial port and control other functions

[ricardons]

Hi

I need to built a pythonfile.py that starts to do a task (monitor at all time a serial port)
And when a certain condition is true(receive a certain byte in serial) start/stop certain functions that I already have.

But is important that the task of reading the serial port is always running and never stops.

So imagine that I have

Readserial() 
  While true:
    Read the serial port (I know how to do this) 

    If readbyte = 0x65: #(for example) 
       Kill or start function1() #(but at the same time Readserial() should continue monitoring serial port) 

    If read byte = 0xFF: #example
       Kill or start function2() #(again readSerial() should continue to run) 

Function1() 
  Do something

Function2()
  Do something 

What is my best solution for this
Threading?
callback?
Watchdog?

If someone give a possible structure I would appreciate since I'm an not an expert at programming
thanks
