ABSTRACT:
A workstation controller is disclosed which operates in either full screen write mode or partial screen write mode. In one embodiment, the controller looks for a "Clear Display"(CD) command in the data stream from the host. If the data stream contains a CD command and if a screen image buffer is available, the controller operates in full screen write mode. Subsequent "Write to Device" (WTD) commands in the data stream are sent to the buffer, not to the device. When the controller detects the end of the data stream the entire contents of the buffer are sent to the display in one operation. If the controller does not detect a CD command in the data stream, or if the CD command is detected but a screen image buffer is not available, the controller operates in partial screen write mode. WTD commands in the data stream are sent directly to the display one at a time.
