Subject: Vertical line is just incremented %2, i'll have to manually buffer

charlcd.c:621

		case '\n':
			/*
			 * flush the remainder of the current line and
			 * go to the beginning of the next line
			 */
			for (; priv->addr.x < lcd->bwidth; priv->addr.x++)
				lcd->ops->write_data(lcd, ' ');
			priv->addr.x = 0;
			priv->addr.y = (priv->addr.y + 1) % lcd->height;
			charlcd_gotoxy(lcd);
			break;
