2.2.4.2.1.18 LINE_MONITORDIGITS

The LINE_MONITORDIGITS packet is sent when a digit is detected. The sending of this packet is controlled with the MonitorDigits packet. The LINE_MONITORDIGITS packet is sent if the client has enabled digit monitoring.

TotalSize (4 bytes): An unsigned 32-bit integer. The total size of the asynchronous event packet.

InitContext (4 bytes): An unsigned 32-bit integer. The opaque, client-specified session value that MUST be equal to the InitContext value that is specified in the original scoping of the line Initialize request.

fnPostProcessProcHandle (4 bytes): An unsigned 32-bit integer. MUST be set to zero when sent and MUST be ignored on receipt.

hCall (4 bytes): An HCALL. The handle to the call or line device that is associated with the asynchronous event.

Msg (4 bytes): An unsigned 32-bit integer. The packet type; MUST be set to 0x00000009 (LINE_MONITORDIGITS).

OpenContext (4 bytes): An unsigned 32-bit integer. The opaque, client-specified context value that MUST be equal to the OpenContext value that is specified in the original scoping of the line Open request.

This information MUST be passed back to the application with each completion and event that is associated with the handle of the line or call on the line. This field is not interpreted by TAPI.

Param1 (4 bytes): An unsigned 32-bit integer. The low-order byte that MUST contain the last digit that is received in a text representation.

Param2 (4 bytes): An unsigned 32-bit integer. The digit mode that was detected. This parameter MUST be one of the LINEDIGITMODE_Constants.

Param3 (4 bytes): An unsigned 32-bit integer. The "tick count" (the number of milliseconds since Windows started) at which the specified digit was detected. For TAPI versions earlier than 2.0, this parameter is unused.

hRemoteLine (4 bytes): An unsigned 32-bit integer. The handle of the client for the line value.
