You mentioned this a long time ago. All that high-level stuff is
supervisory and is completely customizable by the implementor. *However*
you are not likely to see modems which use Rockwell firmware diddling with
that sort of detail very much. When an OEM makes a "really, really
template" AC modem solution he uses a utility called ConfigurACE to
customize a precompiled firmware image, he does NOT recompile the ROM chez
lui. ConfigurACE lets you modify tonedet parameters, power-on defaults, OEM
ID strings, blacklisting, etc etc but it doesn't give you much in the way
of fine control over modem behavior the way customized firmware does.

So I would not expect to see E-series NetComms deviate from Rockwell
defaults, but I *would* expect the M-series 68302-based modems and other
from-scratch firmware sets behave differently from the E-series under
identical conditions (unless NetComm deliberately emulated the Rockwell
decisions).
