### Accessing a Presentation Manager Touch Display Device

Within Presentation Manager, it is not possible to access the Touch device from the following locations:

Presentation Manager program
AVIO window
DOS window (the default)

Under the Properties option on the System Menu, an option has been added called Touch: exclusive to a window, which disables mouse emulation under PM and gives the touch X,Y,Z data directly to the designated window. However, the window does receive full-screen touch coordinates; it will need to perform a mapping unless, for example, it is a graphics program, running maximized, which covers the full screen. In the previously mentioned cases, mouse-emulation mode must be used.

To learn what happens when a DOS program is started in a window and then switched to full screen, and whether a full-screen program can be switched to a window, refer to the OS/2 Physical Device Driver Reference.
