[PyQt] Emulate WIN-DOS Capture results live, How to achive?

[akumarzen]

Instead of os.popen or subprocess to execute SINGLE DOS COMMAND to capture
back its output in python...
Is there anyway I can capture the intermid results simultaneously that
appears in DOS?

Eg:
import os
x = os.popen('ping 127.0.0.1').read()
print x

This print the entire output of PING. But I would like to receive the
RESULTS line by line when PING send out to DOS. Is it possible?
