        const LOAD                      = 1;
        const SUSPEND                   = 2;

msgpack example:

$msg = new DWSCReq();
$msg->c = DWSCCmd::STOP;

$msgpack = new MessagePack(false); // false = disable PHP_ONLY mode
$smsg = $msgpack->pack($msg);

echo var_export(msgpack_unserialize($smsg), true);
