True; it only demonstrates that RockwellRockwell is okay, but
Rockwell->Courier is not (though Courier->Rockwell is apparently ok?)
I wonder if Trev has any stats for connecting to David Drummond or John
Piper or another Courier owner?

Yes, the problem could still be Rockwell's (or Supra's). However I can't
see how putting a Courier on Trev's line demonstrates anything, unless we
think that the problem is not a bug in either a modem but just the lack of
a good quality connection?

This seems reasonable, but is it possible for V.34 to change symbol rate? If
not (and I'd guess not) then it's not possible to shift up to 33.6; the
31.2 connects are at 3200, not 3429.
