Yeah Linux still works exactly this way. The modern WIN32 API even works that way too. When you ReadConsoleInput() it gives you teletypewriter style keyboard codes. When I wrote a termios driver for Cosmopolitan to have a Linux-style shell in CMD it really didn't take much to translate them into the Linux style. We're all still using glorified teletypes at the end of the day. It will always be the substrate of our world. One system built upon another older system.
