In the previous line, all input is read which is not ideal. Depending on the input a single line or part of it should be read so that the script can start working before runner.exe finishes. Now, once you have a workable chunck of the input, you can happily process it and write it out. > if field in packet: > # change it and put it back on the command window and get the > next bunch of stuff > sys.stdout.write() In the previous line, write is called with no arguments. It should recieve the string to output. > I hope my question/intention is clear. The given code is not a working example. It would help if the code was more complete.
