- It would be possible to implement this in the kernel, but much more

- that is accessible to the kernel, which the terminals don't.
- Therefore, the kernel would have to keep track of what is currently on
- the screen. This requires knowledge of the terminal type, and
- interpreting everything that goes to the terminal. And it has to know
- when something isn't supposed to be interpreted, e.g. if the terminal
- isn't a terminal but a terminal emulator program and the user just
- started a download...
-
- This gets messy real soon. It'd be better to avoid it, I think.
-
- But all is not lost. There is a program called `screen' that does
- exactly this. Since it is a user-level program, it can be much more
- messy than if it were in the kernel (if a user-level program is messy
- and has a bug, you might loose some data, if the kernel is messy and
- has a bug, you might loose everything you have on the computer).
-
- Screen should be available for Linux. Can somebody confirm?

- This might be doable with a bootable root-floppy. Most PCs require a
- floppy anyway, and it is easier to do than burning ROMs.

- These are missing, I think.

- Of this I know nothing.
