Цитата из текста по вашей ссылке:

After that I wrote the serial drivers, and voila, I had a simple
terminal program running (well, not that simple actually).  It was still
the same two processes (AAA..), but now they read and wrote to the
console/serial lines instead.  I had to reboot to get out of it all, but
it was a simple kernel.
