You activate binmode like this binmode FILEHANDLE. Here are some examples:

open FILE, "<file.bin" or die "Oops perl says $!\n";
binmode FILE;
my $buffer;
while (read(FILE,$buffer,1024)) {

    # do stuff to $buffer, a 1kB chunk of binary data

}

# you can also binmode standard file handles STDIN, STDOUT, STDERR
binmode STDOUT;
print $binary_data;

binmode STDIN;
# get binary stuff from STDIN

Hope this helps
