   I haven't read that report, but the results you give are not far from what 
I've experienced in the Real World.

   Did they test PEP modems?  If so, I wouldn't mind knowing how they did 
on the noise resistance award (which I would have awarded on the basis of 
lowest drop in throughput as a fraction of best throughput; Hayes might well 
have won that category by having higher raw throughput at a certain 
predetermined noise level).

   At the time, I would think that the 14,400 bps HST with MNP4 would have 
been the fastest modem for compressed data if the protocol used either 
streamed or had a large window.  V.32bis modems can now challenge that, of 
course.
