Actually, you are both right.  The older 1670 (the "three dip switch" model)
cannot detect these sorts of things, and does not respond to ATX2.  The newer
("four switch") model is fully Hayes compatible.  Having had my hands on one
of each of these, I am reasonably sure that this is correct.  The question is,
which model of 1670 does the Aprotek C24 emulate?
