Google is a wonderful thing ;)

(see page 25).

So, to stop the modem from answering incoming calls, try:

     echo "AT S0=0" > /dev/modem         (.. or /dev/ttyS0 or whatever)

and see if that works.  If you've got minicom installed, that might be a
better way of doing this, because you can look for the modem saying "OK"  
in response.

This should work short-term (until the modem looses power), but I don't 
know about long term (a quick skim of the manual wasn't forthcoming) so 
you might want to look out for DIP switches and the like.

Also, see if your "modem software" (chat from pppd, wvdial, ...) is 
setting the S0 register, and undoing the good work above.

HTH

Paul.
