And I would recommend exactly the opposite.  I use my PP2400 SA every
day at 2400 baud.  The signal quality is excellent.  The overwhelming
majority of transmission errors that I've seen were due to my wife
picking up another phone.  The PP2400 SA (the one I've got, anyhow) is
a far better modem at 1200 or 2400 than the Applemodem 1200 which I
gave away after buying the PP.

Have you considered the possibility that you got a bad sample?  Did
you try to return or exchange it during the warranty period?
