  • Are you able to connect with the Arduino on COM8 through the Arduino IDE? – chrisl May 13 '19 at 10:05
  • So in the Windows device manager, what COM ports do you see? – Maximilian Gerhardt May 13 '19 at 15:11

Using clear command on Octave before executing a=arduino('COM8') will remove this problem.

Use it like this:

clear
a=arduino('COM8')
