Editing ANSI escape code (section)

Most Operating System Command sequences were defined by Xterm, but many are also supported by other terminal emulators. For historical reasons, Xterm can end the command with [[Bell character|{{code|BEL}}]] (0x07) as well as the standard {{code|ST}} (0x9C or 0x1B 0x5C).<ref name="xtc"/> For example, Xterm allows the window title to be set by {{code|ESC ]0;this is the window title BEL}}.

A non-xterm extension is the hyperlink, {{code|ESC ]8;;link ST}} from 2017, used by VTE,<ref name="vte">{{cite web |last1=Koblinger |first1=Egmont |title=Hyperlinks (a.k.a.

The Linux console uses {{code|ESC ] P n rr gg bb}} to change the palette, which, if hard-coded into an application, may hang other terminals.<ref>{{cite web|url=https://man7.org/linux/man-pages/man4/console_codes.4.html|title=console_codes — Linux console escape and control sequences|work=Linux Programmer's Manual}}</ref> However, appending {{code|ST}} will be ignored by Linux and form a proper, ignorable sequence for other terminals.{{Citation needed|date=January 2017}}
