[RFC] vgabios over serial

[Rudolf Marek]

Hi all,

I guess it would be not very difficult to add a serial output to VGA BIOS and 
provide int16 serial input aka integrating the sgabios into seabios?

Comments?

Thanks
Rudolf

Are you thinking just text modes or graphics modes somehow? That would
get in the way of any 2way console style communication.

It's possible, but since sgabios seems to work fairly well, I'm not
sure what it would gain.  Keep in mind that sgabios also does serial
port reading (keyboard emulation), vt100 emulation, and can work in
addition to an existing vgabios.
