Module ctrl 

Terminal reset, device-attribute, and version requests.

Category

This module contains terminal-wide control sequences: RIS (ESC c), primary, secondary, and tertiary Device Attributes, and the XTVERSION query.

CSI conventions

Device-attribute requests are 7-bit CSI sequences. Private prefixes (> and =) distinguish secondary and tertiary forms from primary DA.

Mode interaction

These requests do not require a mode. RIS is destructive: it asks the terminal to reset state such as modes, colors, tabs, and character sets.

Constants

REQUEST_PRIMARY_DA

Primary Device Attributes request: exact bytes ESC [ c (b"\x1b[c").

REQUEST_SECONDARY_DA

Secondary Device Attributes request: exact bytes ESC [ > c (b"\x1b[>c").

REQUEST_TERTIARY_DA

Tertiary Device Attributes request: exact bytes ESC [ = c (b"\x1b[=c").

REQUEST_XTVERSION

Terminal name/version request: exact bytes ESC [ > q (b"\x1b[>q").

RIS

Reset to Initial State: exact bytes ESC c (b"\x1bc").
