Low characters are a better choice if you don't mind the gap, since sc has too many magic characters whose magic can't be turned off with a flag line -opost. These chars are 7-13 and 27. Also 0 with scteken. I don't know of any way to reach the glyphs behind these characters using syscons. The cursor would have to have to consist of vertical lines of width 2 or more for it to be translatable across all positions (reduce to width 1 at the gap so that the hardware extends back to width 2). 8x16 doesn't have enough pixels for that. The border has width 1 in most places. Bruce
