The usual mechanism is the pyserial module. Google is your friend. > 2) Can we able to receive data from serial port using python? If yes how? See answer to 1) > 3) Is there any function like "Register event call back”, please explain? > (Register event call back: registers a script to be called when an event > occurs) I believe you need to implement the observer pattern. There have already been several successful implementations of this, and again Google should be capable of finding them. For example: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/131499 > 4) Is it possible "parallel loops" concept in python (In my application > send data to port and receive data should be in one file and execute at > same time)? Most Python implementations support threading, and there are a number of other asynchronous service techniques.
