vector<unsigned char> packet;
packet.push_back(0x61);

packet.push_back(0x62);

// betterbinary string - pass a pointer to Notify along with the size 
m_Comms.Notify( "ACOMMS_TRANSMIT_DATA_BINARY", &packet[0], packet.size() );

m_Comms.Notify( "ACOMMS_TRANSMIT_DATA", string( (char*) &packet[0], packet.size() ) );
