@robinmatz BTW I am also working on Open connection to get the desired port from extra_args. You can also put it in there to open better options for different configurations.

[Harm10]

@robinmatz Can you please respond on my updated PR?

[robinmatz]

@Harm10 , I think I already did. I don't know why you didn't see my reply.

The only thing I asked was for you to run inv lint to ensure proper formatting of your source code ans to commit the modified files. After that, this PR is ready to be merged.

[Harm10]

Weird that your reply has been lost. Anyway I executed inv lint.

[robinmatz]

@Harm10 , could you run inv lint locally to ensure proper code formatting?

[robinmatz]

@Harm10 thanks alot for your work on this! I am thinking about when we to release the next version.

I am waiting for the bug fix #83 to be merged.

After that I think it's a good time to release version 3.1.

As for the other issues you raised, I think we should include them in 3.2

[Harm10]

@robinmatz I am working on another PR to get the port number that can be set in extra_args as well. For that I need some input from you when I create it. But I only have limited time so I would not let version 3.1 wait on it!
