9.1.18 Processing Graphics Commands

Graphics commands, consisting of operators and operands, are sent over an InfoConnect path from the parent accessory to GraphX. GraphX interprets and displays received UTS 60 graphics command sequences. GraphX expects to receive only the commands defined by the UTS 60 graphics command protocol in addition to any extensions.

Generally, GraphX ignores invalid commands, but in some situations, an invalid command may cause subsequent commands to be lost because GraphX may not be able to determine the end of an invalid command. GraphX does not require a complete command to be sent within a single buffer; it accumulates the command arguments until the command is complete and then displays the image.
