Communications
LRC Status
(Longitudinal Redundancy Check)
Usage:
Used when extra data integrity is required.
Definition:
An error-checking routine that verifies the accuracy of transmissions. It is
the exclusive OR of all characters following the STX (start of text) up to and
including the ETX (end of text). What this means is that the binary representation
of all the characters in a transmission are cumulatively added in a column
and each resulting odd integer is assigned a 1 and each even integer a 0
(two 1s = 0, two 0s = 0, a 1 and a 0 = 1). The extra LRC character is then
appended to the transmission, and the receiver (usually the host) performs
the same addition and compares the results.
