LINETERMCAPS  _9R93D

The LINETERMCAPS structure describes the capabilities of a line's terminal device.

typedef struct linetermcaps_tag { 

    DWORD  dwTermDev;

    DWORD  dwTermModes;

    DWORD  dwTermSharing;

} LINETERMCAPS, FAR *LPLINETERMCAPS;

Members

dwTermDev

The device type of the terminal. This field uses the following LINETERMDEV_ constants:

LINETERMDEV_PHONE

The terminal is a phone set.

LINETERMDEV_HEADSET

The terminal is a headset

LINETERMDEV_SPEAKER

The terminal is an external speaker and microphone.

dwTermModes

The terminal mode(s) the terminal device is able to deal with. This field uses the following LINETERMMODE_ constants:

LINETERMMODE_BUTTONS

Button-press events sent from the terminal to the line.

LINETERMMODE_LAMPS

Lamp events sent from the line to the terminal.

LINETERMMODE_DISPLAY

Display information sent from the line to the terminal.

LINETERMMODE_RINGER

Ringer-control information sent from the switch to the terminal.

LINETERMMODE_HOOKSWITCH

Hookswitch events sent from the terminal to the line.

LINETERMMODE_MEDIATOLINE

The unidirectional media stream from the terminal to the line associated with a call on the line. Use this value when the routing of both unidirectional channels of a call's media stream can be controlled independently.

LINETERMMODE_MEDIAFROMLINE

The unidirectional media stream from the line to the terminal associated with a call on the line. Use this value when the routing of both unidirectional channels of a call's media stream can be controlled independently.

LINETERMMODE_MEDIABIDIRECT

This is the bidirectional media stream associated with a call on the line and the terminal. Use this value when the routing of both unidirectional channels of a call's media stream cannot be controlled independently.

dwTermSharing

Specifies how the terminal device is shared between line devices. This field uses the following LINETERMSHARING_ constants:

LINETERMSHARING_PRIVATE

The terminal device is private to a single line device.

LINETERMSHARING_SHAREDEXCL

The terminal device can be used by multiple lines. The last line device to do a lineSetTerminal to the terminal for a given terminal mode will have exclusive connection to the terminal for that mode.

LINETERMSHARING_SHAREDCONF

The terminal device can be used by multiple lines. The lineSetTerminal requests of the various terminals end up being "merged" at the terminal.

Remarks

No extensions.
