This function has too much responsibility. Although it is called "getParamsFromArguments", it actually not only gets the parameters, but also processes them. I suggest to split it into several functions.
This might not be a case for this small program, but usually argument parsing is reused and thus should not contain any specific logic.

I think that in terms of this program timeout is not an error, but expected behavior for closed port. Your solution is ok, but to me it looks cleaner to resolve the Promise with boolean value (true for open ports and false for closed ports). This way you don't need to have empty catch block.
