I just saw this thread, and although I don't follow most of what you
were saying (or even care, really), I do want to comment on two
things you did say.
DB>arena?  As for V.FC, name any other manufacturer other than USR and the
DB>Rockwell chipset stuffers who produced modems that supported V.FC.  Now 
name
Hayes.  Rockwell & Hayes were the ones who developed V.FC
DB>Now name
DB>the company that originated v.32terbo.
AT&T.  I don't remember what year, but it was definitly AT&T and not
USR or Hayes or Rockwell.  And they made their improvment public domain,
so anybody could implement it. USR made their own modifications to it,
making their version proprietary and unable to work with other V.32terbo
modems, but v.32terbo itself was done by AT&T.
Both bits of information comes from Craig Ford's excellent comm primer
that he posts in the Communications echo every month.
