The terminal control sequences that follow the ESC character are dependent on which terminal the control codes were generated for. Many terminal emulators support color and cursor control through a system of escape sequences. One such standard is commonly referred to as ANSI Color. Several terminal specifications are based on the ANSI color standard, including VT100.
<ESC> represents the ASCII "escape" character, 0x1B. Bracketed tags represent modifiable decimal parameters; eg. {ROW} would be replaced by a row number.
Device Status The following codes are used for reporting terminal/display settings, and vary depending on the implementation:
Query Device Code <ESC>[c
- Requests a Report Device Code response from the device.
Report Device Code <ESC>[{code}0c
- Generated by the device in response to Query Device Code request.
Query Device Status <ESC>[5n
- Requests a Report Device Status response from the device.
Report Device OK <ESC>[0n
- Generated by the device in response to a Query Device Status request; indicates that device is functioning correctly.
Report Device Failure <ESC>[3n
- Generated by the device in response to a Query Device Status request; indicates that device is functioning improperly.
Query Cursor Position <ESC>[6n
- Requests a Report Cursor Position response from the device.
Report Cursor Position <ESC>[{ROW};{COLUMN}R
- Generated by the device in response to a Query Cursor Position request; reports current cursor position.
