Cannot connect to Arduino over serial

[craig-coburn]

In my testing, the serial ports in the GUI are listed as a single list and there is no way to select one individually. If I select this one option I get the error in the terminal window:

(base) craigcoburn@Craigs-MacBook-Pro stoneGcodeSender % python gcodesender.py
['/dev/tty.Titanium', '/dev/tty.Bluetooth-Incoming-Port', '/dev/tty.usbmodem2101']
Exception in Tkinter callback
Traceback (most recent call last):
File "/Users/craigcoburn/opt/anaconda3/lib/python3.9/site-packages/serial/serialposix.py", line 322, in open
self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
FileNotFoundError: [Errno 2] No such file or directory: "/dev/tty.Titanium', '/dev/tty.Bluetooth-Incoming-Port', '/dev/tty.usbmodem210"

Here, I have uncommented the print statement that lists out the available COM ports.

Any recommended fixes for this?

Cheers, Craig
