Basic Octave implementation of the matlab arduino extension, allowing communication to a programmed arduino board to control its hardware.

I have an Arduino mega2560 board and it works fine with V0.11.0 including an add-on I wrote. However, when testing things with V0.12.0, I cannot connect with the Arduino anymore. It doesn't seem to be add-on related and I could break it down to simply trying to run scanForArduinos twice in a row without any custom add-ons in the path. V0.11.0 simply gives me the connected device twice. V0.12.0 only works in the first call after arduinosetup() and results in an empty cell afterwards. Trying the 'debug' option gives me: "** initArduino: failed valid response err=1 - Undersized packet header". Could it be that scanForArduinos() doesn't release the connection properly?
I'm new to using a Mac (MacBook Pro, Sonoma 14.4) but have experience with Octave and Arduino in Windows. After pkg load arduino I can see this:
Package Name | Version | Installation directory
--------------------+---------+-----------------------
arduino *| 0.12.1 | .../cathy.zupke/.local/share/octave/api-v58/packages/arduino-0.12.1
instrument-control *| 0.9.2 | .../.local/share/octave/api-v58/packages/instrument-control-0.9.2
>>
The Octave version is:
>> version
ans = 8.4.0
>>
I can run arduinosetup and it will open the Arduino IDE and let me upload the code to an Arduino Uno board. That board can then work with Octave on a Windows machine, but when I try to make a connection on the MacBook I get this:
>> a=arduino('/dev/cu.usbmodem14201')
error: __initArduino__: failed get lib 1 err=1 - Undersized packet header
error: called from
__initArduino__ at line 114 column 12
arduino at line 133 column 16
>>
While more rare, I've also seen this:
>> a=arduino('/dev/cu.usbmodem14201')
error: set: H must be a graphics handle
>>
Unplugging the board and plugging it back in seems to restore it to the "Undersized packet header" state.
For what it is worth, when installing the instrument-control package, there were a lot of warnings but as far as I could tell, no errors.
