Ok, that solves my confusion.
Thanks, Marc.

The problem is, that len('\x90\x06\x00') is not equivalent to
calcsize('Bh'):
>>> calcsize('Bh')
4
>>> len('\x90\x06\x00')
3
Actually calculating the size for 'hB' results in:
>>> calcsize('hB')
3
So far I have not figured out, why there is an additional byte, but it
does not effect the result in

Let's pack this:
In [90]: pack('Bh', 0x90, 0x6)
Out[90]
