Does this Registry key help any:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Unimodem\DeviceSpecific

It lists all the modems installed on your machine

      RootKey:= HKEY_LOCAL_MACHINE;
      if OpenKey('\System\CurrentControlSet\Services\Class\Modem', False) then       if HasSubKeys then begin
        N:= TStringList.Create;
        try
          GetKeyNames(N);
          for i:=0 to N.Count - 1 do begin
            OpenKey(N[i], False);
            s:= ReadString('AttachedTo');
            for j:=1 to 4 do
