[^1]: Some Linux terminals are omitted since they all use the `vte` library behind the scenes. \
      Here's a non-exhaustive list: GNOME Terminal, (GNOME) Console, MATE Terminal, XFCE Terminal, (GNOME) Builder, (elementary) Terminal, LXTerminal, and Guake.
[^2]: The currently released version has a bug where it terminates the response with `ESC` instead of `ST`. Fixed by revision [1.600](http://cvs.schmorp.de/rxvt-unicode/src/command.C?revision=1.600&view=markup)
[^3]: Response is always terminated with `BEL` even when the query is terminated by `ST`.
[^4]: Response to `OSC 10` is always terminated with `BEL` even when the query is terminated by `ST`.

The following shell commands can be used to test a terminal:
```shell
printf '\e[c' && cat -v # Tests for DA1. Example output: ^[[?65;1;9c
printf '\e]10;?\e\\' && cat -v # Tests for foreground color support. Example output: ^[]10;rgb:0000/0000/0000^[\
printf '\e]11;?\e\\' && cat -v # Tests for background color support. Example output: ^[]11;rgb:ffff/ffff/ffff^[\
```
