Windows Terminal Preview 1.15 added support for the little-used DECPS escape sequences, introduced on the VT500 terminals, which allows for simple music playback, similar to the "PLAY" command in old versions of MS-DOS QBASIC. https://github.com/microsoft/terminal/issues/8687 STEPS TO REPRODUCE 1. Run a sample script that contains DECPS escape sequences, e.g. this one from the above GitHub thread that plays the title theme from "Ms. Pac-Man": printf "\e[3;2;1;3;5,~\e[3;8;6;10;8;11,~\e[3;4;10;11;13;10,~\e[3;8;8;11,~\e[3;4;10;11;13;10;11;13;15;17,~\e[3;8;18;17;18,~" OBSERVED RESULT Nothing EXPECTED RESULT It plays the specified music.
