Hi
I cannot find how to read the hexadecimal symbols
given by ethereal (0.10.x)to  get the binary version
of the 2 byte frame control field of the header.
For example:
for a retransmitted probe response frame, I get
:0x0850 which should be read 0580 (with LSB first for
the 8, and MSB first for the 5) to get: 0000 0101 0001
0000
but for a data frame , I get : 0x0208 which I guess
should be read 2080 (with always MSB first) to get
0010 0000 1000 0000 (even if when reading like this I 
get the flag toDS whereas ethereal indicates that it
should be fromDS...)
Am i wrong? Are there different orders according to
the type of frame? how should the hexa symbols be
read?
Could anyone help? thanks in advance.

- Laurent
