    Mach3 parallel port outputs

    A quick question, can Mach3 be configured to use pins 14,16 and 17 as outputs?
    My drivers have an enable line and I would like to have the enable controlled by Mach3. As it sits I have my enable line tied to +5 so the drive is enabled all the time. Standard setup for Stp/Dir, 2&3, 4&5, 6&7 but that only leaves pin 8 as an output.
    Parallel port wiki Parallel port - Wikipedia, the free encyclopedia says pins 14, 16, 17 can be used as input or output.

    Thanks for the help.
    Note, I could install a second PP but I would like to avoid that.

    I believe so, but can't check right now.
    Go to ports and pins, Input pins, and look at the available pins for input. All the pins NOT listed as inputs can be used as outputs.
