Most modems also have a "W" command to wait for a dial tone that you
can add to your dialing/initialization string. However the length of
wait depends on one of the modem registers (may be only two seconds
unless set otherwise). Using this might give you a more fine-tuned
solution than Jack's suggestion but require more work to research the 
fine print re setting it up from your modem manual.

As an example a US Robotics manual I have shows modem register S6 is
used to set the wait time (defaults to 2 sec) and you could change
this to 10 sec with an initialization string of

	S6=10

then prefix all your phone numbers with a (eg.,"W220-2990") to trigger
an up to 10 sec wait for a dial tone before giving up and declaring
the line deal because a dial tone hadn't been heard yet. 

Also since the register setting description reads as if it applies to 
all kinds of dialing it may be possible just to set the register to 
the proper wait time and dispense with the "W" phone number prefix 
altogether.
