assistant: Replying to a message of Bill Cheek to Bill Beogelein:
Rockwell claimed over a million.  But Dataquest at that time said sales were
only about 222K.  I expect something in the middle is more accurate.  Hayes
has shipped FEW modems in the past year and very few during their bankruptcy.
Zoom shipped more modems that Hayes.
Many are still waiting for upgrade chips that various rockwell modem
assemblers claim are not available.
Add about 3 million Sportster V.34/VFC modems and another million Courier
V.34+/VFC modems.  Rockwell claimed to have made 250K chipsets by Dec 94.  So
if they can be believed, there are at least 6 million VFC capable modems now.
But.. in ANY case where V.34 exists, which is MOST of these modems, VFC is of
no importance whatever.
Correct.. not since June 94.. Those still in inventory were made prior to
that time.
If a modem is properly designed.. VFC will NEVER be selected.  V.34 functions
better under all conditions, and does not disconnect if called on to drop
below 14400 bps as VFC does.
Like V.34+<G>
So are PEP (23,000), V.32Terbo (21600), HST (16800), Xpress (9600) and other
protocols that work and work well.
The VAST majority of modem makers do not support these.
MOST just use Dual Standard USR modems which will connect with either.  About
85% according to my Interconnect source.  MUCH of the remainder use Multitech
modems which do not support VFC at all.
ONLY because it is part of a chipset.  ONLY USR offers VFC and doesn't HAVE
TO.  Not all the Rockwell datapump modems offer VFC EVEN though it is in
their V.34 datapump.
I place no importance on VFC at all.  I have had both VFC and V.34 for over
13 months, and once V.34 appeared, it is so markedly superior to VFC I see no
use for VFC whatever.
However, I don't disable VFC either.. So those unfortunate enough to have a
VFC only modem can still get SOME of the performance that the V.34 will
deliver under the same conditions.
