Bytes 9-11 (F4FF44) and 14-16 (X2XX22) are the access control bits. Bytes The first set controls what kind of AC (a pin, a key, or a fixed ac), and the second set is a key number for the ac types that need one. The nibble '4' means AUT. the AUT AC is satisfied when if the appropriate key has been validated using the VERIFY KEY command. The nibble 'F' means NEVR (or NEVER), an AC that can never be satisfied. a NEVR AC does not need a key number and so the example uses X to mean "it doesn't matter what this value is" (this sort of thing is called a "don't care") Substitute 0's for the X's and you will be fine. _______________________________________________ Muscle mailing list [EMAIL PROTECTED] http://lists.drizzle.com/mailman/listinfo/muscle
