How to prevent cura from messing with other serial ports?

[joba1 0]

Hi all,

 

could not find it in the manual or by searching for serial or locking, so I seek for your help.

 

I use Cura on linux (openSUSE) with a USB serial interface printer, and I also have other devices attached on USB serial ports, e.g. an RF-Link and other IoT stuff.

 

Each time I start Cura, it messes with settings of all serial ports, so e.g my connection between RF-Link and Domoticz home automation stops working. 

 

Does Cura respect a locking mechanism? Something like searching for a lock file in /var/lock and not touching those ports? Or how else is this supposed to work?

 

Thanks,

Joachim
