But since you know the range of ports you can calculate the total
number. If you keep a count of how many scanned you can work out
the percentage scanned. You then draw a rectangle the same percentage
of the total width. After each port scanned recalculate the
percentage and redraw the rectangle.

Where's the problem? :-)
