Kind monks,

I'm trying to interface some sort of Card Reader which I have COM object for. However, I can't get the value of the output parameters, but only the returned value of the function.

The 'Is_In' is output (not returned) parameter which suppose to detect the presence/absence of a card in the device.

I've checked COM object with VBScript and it's Ok. My code: 
use Win32;
use Win32::OLE;
use Win32::OLE::Variant;

## Creating the 'Rdr' object - Ok

my $Status;
my $Is_In;
$Is_In = 0;
while (1) {
    $Status = $Rdr->IsCardIn($Is_In);
    print "Is Card In:$Status ; IsCardIn:$Is_In\n";
    sleep(1);
}

The $Is_In variable is never updated.

Can you please help?
