So what you are telling me is that in the following screenshot:-
The value "HELLO" is the human readable one, and the values "4444", "85CCF" and "48004500C0004C004F00" is the non-human readable ones?
Amazing! I had been looking at ST22 dumps since 1997 and had not noticed till you told me.
Actually I was almost 100% sure someone was going to state the obvious and tell me the first line was the useful value, so to try and pre-empt that I wrote "I can see the useful value like the delivery number easily enough" in my original post. Didn't work.
