As long as your dialstring does not contain the @ symbol, then it 
should send CNG (sending tones) when it calls out.  Fax your own voice 
line to test.

The modem firmware is responsible for distinguishing between BUSY, NO 
CARRIER/NO ANSWER, and a valid carrier (CONNECT/+FCON/+FCO).  If you're 
having problems with this, and if your dialstring does not contain the 
@ symbol, then you'll need to refer to your modem manual to see if 
there are some S-registers that can help improve this behavior.  If 
not, then I suggest trying Class 1, and if that doesn't help then 
you'll need to try a different modem model+brand.
