I learned of this undocumented feature from this newsgroup (various
threads a while back - check DejaNews).  The variable TX level of the
Motorola 3400's was suspected to be the cause of some Ascend
connection problems allthough it didn't turn out to be the case (for
me at least).

I assume it allows altering the *TD setting which you shouldn't
normally have to do (altering it probably violates its BABT approval).
You always have to reset the modem after using it so the fully useable
string would be something like ATS39.0=1*TD9&WZ which writes the new
*TD setting to stored profile 1 and then retrieved stored profile 1
(resetting the modem).
