Cw or CCW is easy, either the LED is lit or its not, depends on which way you have the active low setting and motors wired as to which is which.
Not sure what you mean by Line, if step then you will either see the LED light or see it dimming depending on the active low setting you have.
Most BOBs have LEDs on them, or the two I have anyway. I was thinking you were needing something just for testing purposes on your desktop computer without having anything else hooked up.
