👋 @dhruvdabhi101 As @amedina1570 mentioned, `-serial mon:stdio` (especially `mon:`) should enable the QEMU monitor. If you're still experiencing the issue, can you share your development environment details, such as OS?

@dhruvdabhi101 What terminal emulator do you use? What happens with Terminal.app or iTerm2?

@patrickgardella I've created [a release](https://github.com/nuta/operating-system-in-1000-lines/releases/tag/2025-01-25) to share a rebuilt EPUB file. Hope this helps :)

Thank you for the PR! Unfortunately, I'm not accepting new features to keep this OS simple and most importantly, keep it in 1000 lines. Instead may I introduce your work...
