but PPP compression wouldnt explain modem reporting faster speed. Btw I never saw PPP compression enabled in the wild either.

I had a nice US Robotics (or probably 3Com by that point) hardware modem, I have always assumed it was a feature in there somewhere.

Maybe it was PPP instead. It was the effective link speed, not something measured with a download tool.

This would have been ‘97 or so, so my memory is hazy.
