Module c0 

C0 control bytes (0x00..=0x1f).

Category

C0 controls are the 7-bit single-byte control characters shared with ASCII: BEL, BS, HT, LF, CR, ESC, and related communication controls.

7-bit escape conventions

ESC (0x1b) introduces 7-bit encodings of higher-level controls such as CSI (ESC [), OSC (ESC ]), and DCS (ESC P). Those two-byte introducers are emitted by the writer modules for the sequence family they control; they are not represented as distinct constants here.

Mode interaction

Most C0 bytes are mode-independent, though terminals may interpret line-feed behavior according to line-feed/new-line mode (Mode::LINE_FEED_NEW_LINE).

Constants

ACK

Acknowledge control byte 0x06.

BEL

Bell control byte 0x07; also terminates many OSC strings emitted by this crate.

BS

Backspace control byte 0x08; moves one column left in ordinary terminal output.

CAN

Cancel control byte 0x18; often aborts an in-progress escape sequence.

CR

Carriage Return control byte 0x0d; moves to the start of the current line.

DC1

Device Control 1 byte 0x11; commonly XON in software flow control.

DC2

Device Control 2 byte 0x12.

DC3

Device Control 3 byte 0x13; commonly XOFF in software flow control.

DC4

Device Control 4 byte 0x14.

DLE

Data Link Escape control byte 0x10.

EM

End of Medium control byte 0x19.

ENQ

Enquiry control byte 0x05; historically asks for terminal identification.

EOT

End of Transmission control byte 0x04.

ESC

Escape control byte 0x1b; introduces 7-bit escape sequences such as CSI (ESC [) and OSC (ESC ]).

ETB

End of Transmission Block control byte 0x17.

ETX

End of Text control byte 0x03.

FF

Form Feed control byte 0x0c.

FS

File Separator control byte 0x1c.

GS

Group Separator control byte 0x1d.

HT

Horizontal Tab control byte 0x09; advances to the next tab stop.

LF

Line Feed control byte 0x0a; moves down one line, with carriage behavior depending on terminal mode.

LS0

Locking Shift 0, alias for SI (0x0f); selects G0 for GL.

LS1

Locking Shift 1, alias for SO (0x0e); selects G1 for GL.

NAK

Negative Acknowledge control byte 0x15.

NUL

Null control byte 0x00; used as a padding or string terminator in some byte protocols.

RS

Record Separator control byte 0x1e.

SI

Shift In control byte 0x0f; invokes G0 into GL.

SO

Shift Out control byte 0x0e; invokes G1 into GL until shifted back.

SOH

Start of Heading control byte 0x01.

STX

Start of Text control byte 0x02.

SUB

Substitute control byte 0x1a; may also abort an in-progress escape sequence.

SYN

Synchronous Idle control byte 0x16.

US

Unit Separator control byte 0x1f.

VT

Vertical Tab control byte 0x0b.
