Mark:

Awesome!

Of course!

I hadn't gotten to thinking it through that far. Knew there had to be a reason.

Just to fill in completely:

  111  =    0x6F
62319  =  0xF36F

Thnx..

note that 111 in binary is          01101111
and that 62319 in binary is 1111001101101111

so if you just look at the binary then they
both match on the 2nd byte - the one that [3:1]
looks at.

it would have matched a whole load of other
packets that ended 01101111 if you had received any.

as i understand it (ymmv)

cheers,
