Then there is the question of error correction at the various levels in the process. If your software does error correction and your modem does error correction and the network does error correction, each layer adding a few more bytes, you end up with more bytes of error detection/correction than data, and of course more bytes means more chance of error. In some cases, though I can't think of any, the error correcting protocols might interfere with each other. I suppose the answer is to maintain a high degree of cynicism because the world is imperfect and error correcting protocols are too. Bill Ranck
