If you check on the Step pins and have active high chosen you will only see mV, this is because it is a pulse so your meter will not be able to refresh quick enough, using a scope you would see it fine. If you change to active low you should see your 3.5v when stationary but dropping slightly when jogging.
If you check on the Dir pins then you should see 3.5v when you jog one way and 0v the other.
Your problem however may be that your port seems to be the modern type low voltage output and possibly your drives may require more? What kind of drives and do you have a breakout board?
If you use MaxCL mode you will not get the setup right if you have normal Step/Dir drives, MaxCL mode is meant for interfacing to MaxCL machines and outputs signals to specific pins and if I recall correctly the signals are CW/CCW rather than Step/Dir.
