Re: flexfax: problem sending faxes to pxb

Uuuups, 

Matthias is right, I confused the parameters. and I suppose that he 
is also right this may be modem dependent. I just tried this with USR 
and this was the problem. While in adaptive answer it tries to listen 
to the other side tone to determine whether it is a fax machine or a 
modem and it does not emit the tone.
