ESC Sequences

Single-ESC sequences (not starting with [). These include DEC private sequences (ESC #, ESC ( … )), cursor save / restore, character-set selection, and the Fe-class introducers.

Structure

ESC <intermediate>* <final>

• Intermediates: zero or more bytes in 0x20–0x2F (!, ", #, $, …)
• Final: a byte in 0x30–0x7E

For example:

• ESC # 8 — DECALN. Intermediate # (0x23), final 8.
• ESC = — DECKPAM (keypad application mode). No intermediates, final =.
• ESC ( B — designate G0 = US ASCII. Intermediate (, final B.
