LINETERMCAPS
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.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
