To Test that the Dir signal is coming out of the PP you can disconnect the cable and put a voltmeter between the ports Gnd pin and the Dir pin and jog one way then the other, you should see 5V one way and 0V the other. If that works then put the cable back and check at the other end of the cable, if its getting there then put the cable back on the BOB and check the output Dir pins from the BOB.
