It turns out that we had an old version of the upgrade code (V-1440-12),
and should have gone up to V-1440-25. You can get the code from
http://www.diamondmm.com.
..so, as it turns out, it was the modem and NOT the pm3. The PM3 was
performing (and still is, of course minus the missing 33.6k code)
perfectly.
FYI,
