NUT (APC UPS Smart 1400 + ATEN UC232A)

[Joc]

Dear community,

I have an old APC Smart 1400 with a serial connector. It connects to the firewall via an ATEN UC232A adapter.

Does anyone have the mentioned setting working? Unfortunately, I can't set it up. Can anyone help with this?

My attempts revealed the following:

- NUT does not have access rights to /dev/ttyU0.
- If I give the NUT user permission, the plugin works until computer restart.
- If I enter the NUT user with the appropriate privileges in devfs.conf, it will return to its original state after the machine is restarted.

perm    /dev/ttyU0      0660
own     /dev/ttyU0      nut:wheel

- I found a description that I set, but it doesn't work after a reboot either.

I'm clueless. Does anyone have a good solution to this problem?
