LRC Status
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 transmissions 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.
