No I just mean using asio::io_service as a functor queue processor,
but if you use asio you definitely can benefit from its serial_port
class as well.

If you want to see a working code with asio, you can refer to one the
asio examples, but in general I mean the following scheme
// encapsulates yours or asio i/o object, like socket, serial_port etc.
class connection : public boost::enable_shared_from_this<connection>
connection(boost::asio::io_service &io) : io_(io)
void send(data_type data)
// since send() might be called from a client thread, do not
process the data here,
// just post it to the io_ thread(s), where the data will be
delivered to the socket/port
io_.post(&connection::do_send, shared_from_this(), data);
// this method is always called within io_ thread(s)
//issue the signal
void do_send(data_type data)
// send the data
// listens to the connection;
void data_received(data_type data)
