- That's what I thought, at first. But the more I think about it, the
- more I think this is exactly what we should do. Currently, the VC
- scheme emulates the text buffer. If the kernel emulated the full
- SVGA, any program could make full use of the SVGA. It would allow:
-
- o X to run on one (or more) VC's with the others in text mode
- o Different video modes on different VC's
- o other graphics programs (dosemu) to run on VC's
- o Running graphics programs over a serial tty*
- etc.

- Comments?

- (*) The way I see it, if we set up excape sequences for common VGA
- operations (goto such-and-such text mode, etc.) it will not be
- difficult to run DOS programs that use such features over a serial
- tty, so long as the remote terminal can emulate the functions.
