The CommConfigDialog function displays a driver-supplied configuration dialog box.
BOOL CommConfigDialog(
| LPTSTR lpszName, | // pointer to device name string |
| HWND hWnd, | // handle to window |
| LPCOMMCONFIG lpCC | // pointer to comm. configuration structure |
| ); |
Parameters
lpszName
Points to a null-terminated string specifying the name of the device for which a dialog box should be displayed.
hWnd
Identifies the window that owns the dialog box. This parameter can be any valid window handle, or it should be NULL if the dialog box is to have no owner.
lpCC
Points to a COMMCONFIG structure. This structure contains initial settings for the dialog box before the call, and changed values after the call.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
The CommConfigDialog function requires a dynamic-link library (DLL) provided by the communications hardware vendor.
