Something like the following can be placed in /etc/rc.d/<whatever>

	TERM=AT386;export TERM
	setcolor -s On
	
	setcolor -f lgreen,black >/dev/vt01
	setcolor -f lgreen,black >/dev/vt02
	.
	. etc.
	.
	setcolor -f yellow,black >/dev/console

The hardware scrolling option is global and stays active in all
virtual terminals once it's enabled in any of them.  With colors,
setcolor just outputs ANSI sequences, but (which is a little silly)
tests only the controlling TTY for an AT386 tty type.

I complicate the picture a bit, since I prefer 43 line EGA mode
on all virtual terminals.  This requires a small program to open
them one by one and do an ioctl() to set 43 line mode, then use
setcolor to adjust the cursor size.

	v43all
	setcolor -c 6,7 >/dev/vt01
	.
	. etc.
	.

v43all goes something like this:

int main (int argc, char *argv[])
{
	int		vt;
	int		fd;

	dev = vtdev;
	for (vt = 0; vt++ < 8; )

			sprintf (vtdev, "/dev/vt%02u", vt);

		else
			dev = "/dev/console";
		fd = open (dev, O_WRONLY);
		if (fd == -1)
			{
			fprintf (stderr, "Error %d opening %s\n", errno, dev);
			continue;
			}
		switch (ioctl (fd, CONS_CURRENT, 0))

			case KD_HERCULES:
			case KD_CGA:
				fputs ("Incompatible monitor type\n", stderr);
				break;
			case KD_EGA:
			case KD_VGA:
				ioctl (fd, SW_ENHC80x43, 0);
				break;
			}
		}

	return 0;
}

After initially experimenting with this under ISC 2.0.1 & 2.0.2,
I'm certainly happy that ISC have fixed the problem where it didn't
preserve modes across virtual terminals.  Now when you flip vt's
the screen mode changes accordingly (as it should).  I'm also glad
they've put in the ^[= sequences which makes setcolor possible.
