gross weight, N net weight, and T tare weight. /P and /S can be used to specify primary or secondary.
Minus indicates sign inclusion, and (0) indicates leading zeros. First digit indicates field width in
characters. Decimal indicates floating decimal point. Decimal with subsequent digit indicates fixed
decimal with n digits to the right of the decimal. Two consecutive decimals (for example, <W06..>)
send the decimal point even if it falls at the end of the transmitted weight field.
<tttttt> Tare weight. See description above.
<EOL> <CR> is entered at the end of the string as the end of line character in this example.
