发明名称 NOCHANGE attribute mode
摘要 An improved display controller provides commands for changing a display. The controller includes a component for determining whether or not the command provided thereby includes an attribute changing command therein. If a NOCHANGE mode has been set, and the controller component determines that an implicit attribute changing command is included in the display command, the attribute changing command is inhibited. If a direct, explicit, attribute changing command is detected, the attribute change is performed. If the NOCHANGE mode has not been set, all attribute changing commands are executed, whether implicitly or explicitly provided.
