I have had similar problems with the 212 Upgrade to my AppleCat.
Each time, I have been able to solve the problem be simply moving
the upgrade card around.  It seems that the card (which is not
directly plugged into the bus, but is hanging outside of the case
by the connecting lines) sometimes is grounded against something
on the backplane.  I've also found that soldered connections on
the large ribbon cable to the upgrade card were fragile and could
come loose.  Results were that 300 worked fine, but 1200 baud was
a sometimes a problem.  When I solved these minor hardware
problems, the Novation worked just fine--much better than the
Hayes compatible external modem that I'm using with my IBM clone.
The filtering is much better and is less susceptible to line
noise.
