I was today years old when I learned that you can connect to a DOS machine over a serial line. 🤯🥴

Do ctty com2 in DOS and then something like minicom -D /dev/nullmodem -R cp437 -b 9600 on Linux, for example.

It literally only redirects stdin/stdout/stderr on DOS, which limits what you can do quite a bit. Launching edit, for example, starts the editor on the normal screen and you have to use the actual keyboard to control it.

(It’s probably useful to note that you can back to normal operations using ctty con.)

Those 9600 baud are pretty slow and they make it feel like you’re sitting in front of an old machine where even dir prints line by line, slowly.

Fun stuff. 😅
