serial= serialport("/dev/ttyACM0", 9600)
error: serialport: Error opening the interface: Operation not permitted
The teminal program putty has no problem with the port. I am in
the group plugdev of the port that has read/write permission.
Octave is started with ‘snap run octave --gui’. Could snap cause the problem?
