parport observation in outport out-inverter-1 seems not to work

2.9.7 I can't manage to start a configuration with inverted output ports.

pin 1-14-17 out-inverter-1 seems not to work

I can change state, but I can't start a setup with an inverted state

video     That's what I did when I ran into the problem

I tried what you suggested, it doesn’t work, it has erratic behavior. It performs poorly in 2.8, 2.94, and 2.97, it behaves erratically in all of them, I don’t understand what’s going on

What does "erratic behavior" mean, exactly and how does it show up?

At startup, the system,(for example the pin 1-out) does not change when an inverter is applied.
You can watch the video I uploaded in this thread to see what happens

I'm a bit confused, if I want to start the system with an output at 1, do I apply setp... inverter true

This should show me the output activated, but I don't see it that way; I still see it turned off. I don't know if I'm misinterpreting it or if it's not working for me, which is why I left a video showing it.

I think you may be misinterpreting how the invert parameter operates,
it does not change the state of the parport.0.pin-NN-out hal pin.
(It cannot as this hal pin would be driven by a hal signal)
but rather changes the physical output polarity. You cannot
detect this change in the parport.0.pin-NN-out hal pin but only by
measuring the actual parallel port hardware output pin.
