We started down the path of implementing support for DIY SimWind devices and ran into some road blocks. Sim Commander only opens COM ports for devices that it knows about. This prevents all manner of problems when we attempt to co-exist with other simulation software, none of which make any attempt to co-exist. Other simulator software will open every COM port on the system and try to talk to them, sometimes leaving them open and blocking other apps from getting to it.
There is no way to identify a DIY sim wind device before opening the COM port unless we were to make some custom firmware for it. Unfortunately, no one here has the time for such a task, so the concept is dead in the water.
Simply put, we cannot sacrifice reliability and our ability to co-exist with other software in order to support these DIY devices.
