It _is_ possible to turn off call waiting on INCOMING calls, if you 
also have Three-Way Calling.  Instead of having your modem 
auto-answer (S0 > 0), you need to look for RING messages or the RI 
lead and answer by command.  Instead of just doing an "ATA", do 
this:  "ATH1D,!,*70,;A".  This causes the modem to go off-hook, 
hook-flash, disable call waiting, and then answer.  On some central 
offices, it is necessary to put another "!" before the semicolon.
