Note that EK-VT100-RC-001 contains several errors and omissions. The errors appear to all be fixed in the posted version. Here are some additions:
Parameters to Direct cursor addressing can be omitted if 1. "Index" is broken if NEWLINE is enabled (set-up). "Reverse index" scrolls up retaining the same column. CHARACTER SET DESIGNATORS: G0 = Shift-In, G1 = Shift-Out > ANSI/VT52 mode ANSI N/A VT52 ESC [?2l ANSI/VT52 mode ANSI ESC < VT52 ESC [?2l Modes can be combined using ";", for example "ESC [ ? 3 ; 4 ; 7 h" CONFIDENCE TESTS: Parameter bits are summed into one parameter. Hardcopy ESC # 7 Graphic processor ON ESC 1 Graphic processor OFF ESC 2
The reference card showed incorrect graphics for octal code 140; its correct graphic is ` (accent grave).
