@NekoEd @koko I do most of my DOS development in emulators which are obviously easier to work with, but when I needed to do it on hardware, I set up mTCP to download a new version of the code on boot, and I'd test new code by just hitting ctrl-alt-delete.
It's easy to set up a basic web server with python, since you can just do a one-liner for it.
