Linuxcnc keeps the port connected when exiting

Good evening my friends, I'm using a parallel port, and I have a problem that when I close Linuxcnc the last ports that were activated continue to be activated even with Linuxcnc closed, when I open Linuxcnc again it turns off the outputs correctly, is there any way of doing this? reset all outputs when it is closed? I'm using Linuxcnc 2.9.2 on Debian 10 with the parallel port that comes on the motherboard. can you help me?

Best way would be to use a charge pump, can be easily made with a resistor, two capacitors and a darlington transistor, but will probably require rewiring.
There might be a way to reset the parallel port by editing the shutdown.hal file and adding ... probably just
loadrt hal_parport cfg="0x0378 out", just not sure if the driver will be unloaded before loading it again by this.
Still, easy enough to give it a try...

Can you explain to me how I can make changes to this file? I'm new to Linuxcnc.

Might be out of date:
wiki.linuxcnc.org/cgi-bin/wiki.pl?About_Charge_Pumps
forum.linuxcnc.org/16-stepconf-wizard/1869-charge-pump

From the docs:
linuxcnc.org/docs/2.9/html/man/man9/charge_pump.9.html



Should be a start

the shutdown didn't work for me, the outputs still remained connected when closing Linuxcnc, and the charge pump will not be viable, the electrical is ready, in the last case I will try it, but there is no way to edit the .axisrc for when Linuxcnc asks If I want to exit and press yes, it turns off all outputs before

Something like
setp parport.0.reset
in shutdown.hal might work, but not sure of the exact pin/command name is or would have to be, sorry no parallel port here to try. That might also need a value or true...

I tried everything, but I think the shutdown didn't work, is there any other way? I will have to change the electrics on my machine then

Did you add the shutdown.hal entry to the ini file?

yes I did,
SHUTDOWN = shutdown.hal
then I added it inside the shutdown.hal

loadrt hal_parport.0.reset 1

setp parport.0.pin-17-out-reset 1

Good afternoon, I came to ask for help once again, a while ago in this post I asked a question and they told me the charge pump, I have some doubts, I saw in the video that they put the link that the charge pump activates a relay, so that Would this relay be exactly? I saw the video, but I don't speak English, I translate everything, then I didn't understand much because I couldn't translate
