Enable Host Graphics
Enables the 3270 host graphics function. Host graphics is the display of lines, circles, ellipses, filled areas, images, and other graphics primitives as defined by the graphic orders of the IBM 3179G Color Graphics terminal. See the supported orders table for more information.

The default is No.

Character-Cell Size
The cell characteristics used for host graphics.

Select Automatic if you use host applications that redraw graphical pictures according to a Usable-Area Query Reply or a Character-Set Query Reply sent by the terminal. This is the case when you use host applications under GDDM, and in some other graphical environments. Selecting Automatic causes the cell size returned by the Usable-Area Query Reply and the Character-Set Query Reply to change according to the Host On-Demand window size.

Select a fixed cell size if you use host applications that assume Terminal Usable Area to be a fixed coordinate space. Select the appropriate cell size for your application. For help selecting an appropriate cell size, refer to the character-cell-size table.

Automatic is the recommended selection. Choose a fixed cell size only if the application does not display graphics correctly for the automatically-chosen size.
