Originally created by @mataha on GitHub (Jun 21, 2023).

Rather than a feature, I have a question regarding both Terminal and conhost.exe:

Is there a way to make the terminal emit CRLF through ANSI escape sequences?

Use-case: we (in a thread here) are trying to create a customizable prompt for cmd.exe with the aid of virtual terminal sequences. What we have currently is emitting DA (\e[0c) and creating a DOSKEY alias for the response (which is always \e[?1;0c). However, for that to work the macro would need to be executed somehow, hence the requirement to inject an Enter there.

Example PoC should that be necessary:

@setlocal DisableDelayedExpansion & echo off

for /f "skip=1" %%e in ('"echo(prompt $E| "%ComSpec%" /d /q /k 2>nul"') do (
    set "\e=%%~e"
)

"%windir%\System32\doskey.exe" %\e%[?1;0c = echo ...

set PROMPT=$E[0c$P$G$S ...
