Please read the documentation under /usr/src/usr.sbin/pcvt/Misc/*/.
(Yeah, i'm going to install it somewhere under /usr/share/doc.)

Btw., on a VGA, you can define the exact RAMDAC values for each color
if you want, different for each VT.  Makes them visually disting-
uishable.  One of the things i'm so proud of. :-)

Yes.  Please, contact Hellmuth Michaelis (hm@altona.hamburg.com) for
this.

Intention.  You can change it in a header file, for a future version
you'll be able to override it with a config option.

All kernel printf's are printed white on red; i believe this was
Hellmuth's idea to give them some "warning appearance".

Hellmuth, and me as a co-author and FreeBSD maintainer.

Again, make sure you've set your TERM variable correctly.

It has other ideas of the color mapping (both are certainly
gratuitous, as somebody else wrote you, there's no such thing as
"bold" on a color console).  You're the first one i know of who's
complaining about it's color assignments...

It's certainly got more functionality than syscons wrt. DEC VT style
emulation, while it misses all the SCO compat cruft.  Both is by
intention.

Never trust an operating system you don't have sources for. ;-)
