Output Parallel Port
------ -------------
X direction D0, pin 2
X clock D1, pin 3
Y direction D2, pin 4
Y clock D3, pin 5
Z direction D4, pin 6
Z clock D5, pin 7

Input Parallel Port
----- -------------
X/Y/Z lim + S3, pin 15
X/Y/Z lim - S4, pin 13
X/Y/Z home S5, pin 12

For bridgeportio the digital in bits are on the Status port. The index #s 0
thru 5 corresponds to bit #s S3 thru S7). The digital out bits are on the
Data port and the Control port. The index #s 0 thru 7 correspond to D0 thru
D7 and index #s 8 thru 11 correspond to C0 thru C3.

Hope this helps!
