LINE_MONITORDIGITS
    htLine = (HTAPILINE) hLineDevice;
    htCall = (HTAPICALL) hCallDevice;
    dwMsg = (DWORD) LINE_MONITORDIGITS;
    dwParam1 = (DWORD) chDigit;
    dwParam2 = (DWORD) LineDigitMode;
    dwParam3 = (DWORD) dwTickCount;

  • htLine
    The TAPI opaque object handle to the line device.
  • htCall
    The TAPI opaque object handle to the call device.
  • dwMsg
    The value LINE_MONITORDIGITS.
  • dwParam1
