> This is what the debugger outputs for parsing one of the tests for
> mil-std-2045, test2045msghdr1.
> It detects that this is bitOrder leastSignificantBitFirst data and so
> presents the data Right-to-Left order, which is good.

> However, this is gibberish, as the bytes of this data (left-to-right) are E4
> 67 00 80 55....
> So presented Right-to-left the values in the bytes shouldn't change. But if
> you look at the data dump above, the bytes are 4e 76 00 08 55.... which means
> the nibbles of each byte have been swapped.
> That's just plain wrong. Bit order doesn't change the numeric value of any
> byte.
> These displays are useless.
