	The problem you mention is one that is true of the early 1670
modems.  The 1670 is only partly Hayes compatable.  The early 1670's
(which appears to be yours and mine) disable auto-answer only by use
of an AT command.  Current 1670's do have a dip-switch to disable.

	As an aside, only a few of the "Hayes" commands were put in
when the modem was released, but the cost was $170-190 compaired
with a then Hayes cost of $400+.  Part of this is a function of
the economics.
