NEC SV9300

I try this for a NEC SV9300 but not work. I miss something?

```
const SmdrClient = require('nec-smdr');
const smdrClient = new SmdrClient({ host: 'x.x.x.x', port: 60010 });

// A la escucha de eventos
smdrClient.on('any', event => {
  console.log('Nuevo evento');
  console.log(event);
});
```
