Graphics Instructions
All graphics instructions begin with the escape character (ASCII 27) or ctrl-Z (ASCII 26), depending on the setting of a configuration switch. A letter after the escape character identifies the instruction, and is followed by a number or series of numbers modifying the instruction. For example, ESC E n displays the nth full screen graphic stored in EEPROM, where n can range from 0 to 15.
Numbers can be expressed either as ASCII text (e.g. "123") followed by a throwaway character, or as single-byte shortcuts. Shortcuts are the one-byte sum of the number to be sent, plus 64. Numbers up to 191 can be sent this way to increase serial throughput. See the user manual for examples.
