Here the phone co. changes the tone if the line has some special
services to something that sounds like the busy tone, and as such is
recognized by the modem. I found that my modem uses X3 in the init
string to stop waiting for dial tone (X4 in normal conditions). You
can find out in window$ if you have it with dual boot using it's
drivers: in the advanced item of the modem properties activate
logging. This writes all the commands sent to the modem to a text file
in c:\windows\ (i don't remember the name, look in the help). Then
dial. Uncheck the "wait for dial tone" box, an redial. Then read the
log and compare the two init strings. You'll find the one for it.
Now, if you don't have the big bad os and the modem's manual don't
tell you how to do it, call the makers of the modem. Maybe they help
you out.
Hope this helps
