The status byte is built from the binary values of the display indications (tare, zero,
gross/net and stability). 20h is added to the result to ensure that the result is
printable.
Bit 0 (01h) The transmitted value is the gross weight.
Bit 1 (02h) A tare is set.
Bit 2 Not used, always 0.
Bit 3 (08h) The indicator is set to zero.
Bit 4 Not used, always 0.
Bit 5 Not used, always 0.
Bit 6 (40h) The weight is stable.
Bit 7 Not used, always 0.
