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.
