From 4d2e28bf2d22ddea9372839721cc6c33d2c526c7 Mon Sep 17 00:00:00 2001 From: songziming Date: Mon, 22 Jul 2024 17:52:55 +0800 Subject: [PATCH] chardev/char-win-stdio.c: restore old console mode MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If I use `-serial stdio` on Windows, after QEMU exits, the terminal could not handle arrow keys and tab any more. Because stdio backend on Windows sets console mode to virtual terminal input when starts, but does not restore the old mode when finalize. This small patch saves the old console mode and set it back.
