 CHK (check sum)
LRC (Longitudinal Redundancy Check) is calculated by summing up the values of the
bytes from ADR1 to last data character then calculating the hexadecimal representation
of the 2’s-complement negation of the sum. For example, using the command message
of above:
STX ‘:’
‘0’ ADR 1
ADR 2

‘0’ CMD 1
CMD 2

01H+03H+21H+02H+00H+02H=29H, the
2’s-complement negation of 29H is D7H.
