Hello,

The Digital Equipment Corporation DF224 (Scholar) modem supports V22A
(1200) and V22B (600) as well as V22 BIS (2400).  The documentation
that I have indicates that the modem will fallback to 1200 b/s from
the V22 BIS mode; however, as the documentation I have is preliminary,
I cannot say whether the fallback protocol can be switched between V22A 
or Bell 212. When my modem has fallen back, I think it has gone to Bell 
212 - though I cannot be certain.
