Hi Gerd,
I was curious to see what the "sercon" stuff would look like in
SeaVGABIOS instead of in SeaBIOS. So, I put together a quick
prototype. The code is also at:
https://github.com/KevinOConnor/seabios/tree/testing
This is just a proof-of-concept thing - I didn't implement any of the
useful features you have in your series. Specifically, it doesn't
unclutter the serial output, doesn't implement cp437 translations, and
doesn't handle multi-byte input. It does does have basic input,
output, and split-output handling though.
I'm not sure if this is better than a SeaBIOS implementation. I
suspect it will be easier to handle vga quirks this way. However,
handling exotic serial outputs (eg, mmio and usb based) would be
better suited in SeaBIOS.
Thoughts?
-Kevin
