First of all, I should have included that my system is per se, a sub par system. It's an AMD K6-2 450mhz processor so every little tweak counts. I mentioned that you probably wouldn't see much difference on a high speed line and maybe the same goes for a monster system, unlike mine. If someone has a nominal system similar to mine, I would like to see their results. Again, the transfer rate coming in from the phoneline has no bearing on this tweak. The tweak only increases the rate your modem grabs the info from the phoneline and sends it to the rest of your system. I wouldn't be here wasting my time with all these posts if I didn't see a difference in performance on my machine. Just trying to help others.
