The difference is in what the modem looks at and what it reports.  As I read 
your question you wanted to be able to dial without the modem recognizing a 
dial tone (recognition is part of 'adaptive dialing').  In the Courier line 
settings of X0 and X1 disable it, most Sportsters will work the same, an AT$ 
should tell you.
