CommConfigDialog info Overview Group

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.

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.

The CommConfigDialog function requires a dynamic-link library (DLL) provided by the communications hardware vendor.
