Sms messages (in-out). What functions do I need?

[nfrfab]

Hi, I have this problem:
I need my app detects incoming sms, process the sms, and finally responds (automatically).

I do not know what functions need (I do not understand the information in https://developer.blackberry.com/cascades/reference).
To send sms:

• use the class SmsTransport
  @
  ...
  m_smsTransport = new SmsTransport(this);
  connect(m_smsTransport, SIGNAL(messageReceived(unsigned int, const Message &)), SLOT(messageReceived(unsigned int, const Message &)));
  connect(m_smsTransport, SIGNAL(messageSendResultReceived(bb::pim::message::MessageKey)), SLOT(messageSendResultReceived(bb::pim::message::MessageKey)));
  m_smsTransport->registerPort(1);
  ...

void MainWidget::messageReceived(unsigned int puerto, const Message & mensaje)
{

}

void MainWidget::messageSendResultReceived(bb::pim::message::MessageKey messageid)
{
//check status

}

@
when I need to send a sms I use
@
void MainWidget::enviarmensajesms(unsigned int puerto, const Message & mensaje)
{
m_smsTransport->send(puerto, mensaje);
}
@

I have not a real device, I can not test the code. Need anything else? How register ports for incoming messages? Thanks for help.
