I have also had trouble with the Toshiba 2400 bps internal modem
connecting at 2400 bps with the USR Dual Standard operating with V.32
answer tones.  On the advice of USR I set S28=0, which minimizes the
length of the V.32 answer tones.  This solved the problem for the
Toshiba modem, but other brands (including Everex) still have problems.
They also have trouble connecting to a MultiTech V.32 modem at 2400
bps, so I suspect that these modems don't react well to the V.32 answer
tones.

By the way, Toshiba technical support was no help at all, in spite of
the fact that they use a USR Dual Standard themselves on their BBS.
This all occurred in January or February of this year.
