Re: LRC (longitudinal redundancy check) and Even Parity

I was calculating the LRC before setting even parity. I'm hoping that was my problem. If so, this is the change that I made, in case anyone else can find use in these functions: /************* LRC ************************/ /*** taken from Perl module String::LRC ***/ function lrc($buffer) {

    $len = 0;
    $buffer = setEvenParity($buffer);
    if (isset($buffer) && !empty($buffer)){
        $len = strlen($buffer);
    }
    $check = substr($buffer, 0, 1);
    for ($i = 1; $i < $len ; $i++) {
        $check ^= substr($buffer, $i, 1);
    }
    return $check;

} We'll see how this goes tomorrow. Dominic
