GDDMXD/MVS is an interface that allows graphics from the IBM® Graphical Data Display Manager/MVS to be displayed on workstations that support the X Window System. When GDDMXD/MVS is installed and activated, the data stream created by the GDDM® application is translated to the X Window System protocol and transmitted by TCP⁄IP to the X Window System server for the display. If GDDMXD/MVS is installed and not activated, or has been made inactive, the GDDM application transmits data to its supported display device as if GDDMXD/MVS were not present.
