### Pen Device Objects

Pen for OS/2 system extension device objects are Workplace objects that provide a means of communication between a computer and another piece of equipment. The Locator object enables the configuration of barrel button settings and hardware that is of the absolute locator device type (LOCTYPE_ PEN and LOCTYPE_FINGER). The Display object enables the configuration of LCD display devices and bezel buttons and provides a means for the user to set the timeout for the backlight.

If you supply hardware devices that will interface to the Pen for OS/2 system, you must create a similar object or subclass one of the objects included with Pen for OS/2.
