bde 91a5e56364 Don't allow negative console numbers for the VT_WAITACTIVE ioctl. Use the ... correct console number for the VT_WAITACTIVE ioctl. Invalid console numbers caused waiting on an invalid pointer. Use bcopyw() instead of move_up() and move_down(). bcopyw() handles overlapped copies and should be faster. Actually use bcopy(). bcopy() is slightly faster if video memory is 16-bit and about twice as fast if it is 32-bit. bcopy() is said to fail on someGA's, but syscons already depends on it working for other accesses to video memory.		1995-01-03 16:56:05 +00:00
