How to use the COM interface in simulations

[michielper]

I have read that it is possible to create COM objects with Javascript in a simulation (e.g. of a State Machine). And it should even be possible to communicate between an EA simulation and another application or system, using these COM objects. However, the documentation on this is not sufficient to understand how to do this.

So, my question is: How do I create and use a COM object to communicate via a serial port (USB) from a simulation?

Follow this (C#) guide for how to make a class visible.

This page describes how to call it from within a simulation.

I can't help with communicating via a serial port, it's a little too far outside my expertise.

You could perhaps look at the SerialPort in System.IO.Ports

Note that if I recall correctly you can't access I/O direct in C# like you can in C++ so if you want direct access you need to use C++.
