MacOS Ventura "plover.machine.stentura._ConnectionLostException" using Stentura 6000

[jenniwritescode]

Description

Stentura 6000 will not connect to Plover running on MacOS Ventura.
Plover DOES work on the same computer running Windows 10 bootcamp.

Steps to reproduce

Configure using instructions in the Wiki for 400 SRT - error occurs regardless of baud rate or type of realtime connection (6000 or 6000+ are the options).

Expected behavior

Stentura should say "connected" in Plover window.

Actual behavior

Attempts to initialize, then says disconnected.

Log shows following information:

Hardware Config: USB 2.0 hub > Keyspan USB to Serial adapter > null modem cable > Stentura

Discussion
I am able to connect to the Stentura using Serial2 and was able to get to the "Stentura 6000 Communication Menu" in the emulator.

Stentura is in realtime mode and showing "Communications: ACTIVE"

Adapter drivers are installed and show in System Information and in /dev as both a cu and tty port. The cu serial port is selected in the Plover configure screen.

I used Homebrew to install Plover and the version of Python on my machine is 3.9.6.

Have tried reinstalling, removing the plover.cfg file and reloading Plover.

I believe this is an issue with the app for Mac OS as this setup works on this computer using Windows 10 bootcamp.
