I think that kind of behaviour was built up, piece by piece, as the
protocols were introduced one by one.
As such it is a bit of a mess.
It is also in that area that individual manufacturers are most likely to
have changed the behaviour of the Rockwell supplied reference
implementation, first to fix particular problems and later for
compatibility with their earlier fixes :-(
I think that I am right to say that the key to understanding settings at
this level is to watch which S register value changes the modem commands
make. The way these modems seem to work is that the AT commands set S
registers & the modem decides how to behave according to S register
values. It is only perhaps with the AT+MS settings that this model may
first have been broken. Do you understand?
