we use a Gateway, which uses the USB Network Gate library. We want to use it over the Internet from Germany to Australia and there over a 3G connection. So the connection is extreme slow.
If TCP repetitions occur due to a slow Internet connection, the USB device may also receive duplicate USB telegrams.
This is a problem for our USB device as it cannot handle duplicate telegrams.
Does anyone know the problem? Normally, the TCP protocol itself ensures that telegram duplicates do not arrive at the application. Why is this the case here?
