Original Pull Request: https://github.com/microsoft/terminal/pull/14214

State: closed
Merged: Yes

Silent MIDI notes can be used to seemingly deny a user's input for long
durations (multiple minutes). This commit improves the situation by ignoring
all DECPS sequences for a second when Ctrl+C/Ctrl+Break is pressed.

Additionally it fixes a regression introduced in 666c446:
When we close a tab we need to unblock/shutdown MidiAudio early,
so that ConptyConnection::Close() can run down as fast as possible.

Validation Steps Performed

  • In pwsh in Windows Terminal 1.16 run while ($True) { echo "`e[3;8;3,~" }
    • Ctrl+C doesn't do anything ❎
    • Closing the tab doesn't do anything ❎
  • With these modifications in Windows Terminal:
    • Ctrl+C stops the output ✅
    • Closing the tab completes instantly ✅
  • With these modifications in OpenConsole:
    • Ctrl+C stops the output ✅
    • Closing the window completes instantly ✅
