spindle control of PM-728vt using linuxcnc

Thank you for the information.
I already have pins out-07 and out-08 defined and pulled to the PM-728vt but NOT connected.

If i do a MDI m3 command the halcmd looks like this:
    26  bit   IN          FALSE  hm2_7i76e.0.7i76.0.0.output-07 <== spindle-ccw
    26  bit   IN           TRUE  hm2_7i76e.0.7i76.0.0.output-08 <== spindle-cw
