What's new:
- More accurately report why VU server failed to start.
Only one instance of VU server is allowed. When VU server is already running and you start another instance, the second one will fail to start as expected. However the error message would say "VU Server crashed during start up" which is true but can also be confusing/misleading.
Now when you try to start the second VU server instance, the error message will indicate that there was a serial port access problem which hints that VU server is already running.
