This is a new function in Driver488/W95 and in Driver488/WNT. This function is similar to the
MakeDevice
function except that
MakeNewDevice
will create a new device based on the parameters
specified, instead of simply cloning an existing device.
The
MakeNewDevice
command does not save the parameters of the newly created device in the system
registry. To keep the device, it is necessary to call the
KeepDevice
function.
Note: The
MakeNewDevice
command will only create, not save, a new device. Interface
descriptions are created and maintained by the configuration utility and the IEEE 488
configuration applet in the Windows Control Panel.
