    Does anyone out there have Racal Vadic VA 4224 modems installed ...

    p.s. Interesting point.  These suckers talk (2400/1200/300) but the
    protocols supported are (V.22/212/103).  Note: Vadic 3400 protocol is
    not supported!

  A few years ago, Vadic 3400 and Bell 212 were equally popular.  For a
while it looked like Vadic 3400 was pulling ahead.  But now, it seems to
be one with the dinosaurs.
  This is unfortunate, since Vadic 3400 was a better protocol.  Does anyone
know why Bell 212 came out ahead?  Restrictive licensing by Vadic, perhaps?
