I have solve this issue creating a new thread to manage data:

MyUserClass::OnDataReceived()
{
  // Create New Thread
  try {
    _read_thread_ptr.reset( new
boost::thread(boost::bind(&MyUserClass::ManageData, this)) );
  } catch (boost::thread_resource_error e) {
    // Failed to create the new thread
    return;
  }
}

But another problem is raised: when I receive 2 command one after other
quickly, I miss the second, so...

Is there a method to launch a signal directly into another thread?
Something like:

boost::thread(boost::bind(signal_OnData, ptrToObj))

thanks in advance!
Daniele.
