>>Popen(args='c:\\WINDOWS\\system32\\command.com' Don't launch command.com, try running the actual program you are interested in in capturing the text for. Although you should be able to run the command interpreter too- I don't know why that didn't work.
There are several variations of popen, so you may want to explore them all to see which suits your needs. -- http://mail.python.org/mailman/listinfo/python-list
