Reverse index
(RI)
ESC M This is an 8-bit control character (8D hexa-
decimal) that can be expressed as an es-
cape sequence for a 7-bit environment. RI
moves the cursor up one line in the same
column. If the cursor is at top margin, the
display scrolls down.
Next line
(NEL)
ESC E This is an 8-bit control character (85 hexa-
decimal) that can be expressed as an es-
cape sequence for a 7-bit environment.
NEL moves the cursor to the first position
on the next line. If the cursor is at bottom
margin, the display scrolls up.
Save cursor
(DECSC)
ESC 7 Saves the following into memory: cursor
position, graphic rendition, character set
shift state, state of wrap flag, state of ori-
gin mode, state of selective erase.
Restore cursor
(DECRC)
ESC 8 Restores the states described for DECSC.
If none of these characteristics were saved
the cursor moves to home position, origin
mode is reset, no character attributes are
assigned, and the default character set
mapping is established.
