[hylafax-devel] Re: Modem Reset Commands

Dmitry,

We are listening!!

It took a bit of correspondance back and forth for it to become clear from 
you that ATZ reset the data pump.

Also, the fact that you were/are advocating relying on the ATZ setting the
modem to a KNOWN state muddied the waters a bit as well.

I haven't seen anyone argue against using the ATZ once it became clear that
it does MORE than just program the modem to the NVRAM settings ( which was
my understanding prior to this whole conversation ).

Anything that can be done to reset the modem to a know state is good.

ATZ followed by reinitializing paramaters seems to be an excellent way to
go.
