	I don't think I'd want to work with any device where 0x10 (00010000
binary) modifies bit SEVEN. 0x40, OTOH, would fit my mental impression
of bit 7.

	It doesn't even fit my mind if the value is suppose to be the /bit
number/ unless the device considers "bit 7" to be the EIGHTH bit (that
is, the LSB is considered bit 1, not bit 0)
