Hi,
I answered you on your support request. For other people who could be interested, here is a copy of my answer
Hi Michael,
There’s no reason IntuiFace would block a port and it can launch a batch file using the Launch application.
Could you please send us your batch file so we can test on our side?
In the meantime, we developed a quick sample that you can download here that sends UDP commands directly from IntuiFace.
We used PacketSender to test that messages are correctly received.
You could maybe replace your batch with some IntuIFace actions using the custom Interface Asset in that sample.
