Re: [Boost-users] Asio problems with async_read

      Hi

Here is how I call the function

I have splitted it in two like this, because the protocol specifies a
timeout pr. character and not pr. message

std::vector receive(boost::asio::io_service & io,
boost::asio::serial_port & cctalk_port, size_t size){
     std::vector v;
     size_t i = 0;

     while( i < size ) {
         std::vector _v = receive(io, cctalk_port);
         copy(_v.begin(), _v.end(), std::back_inserter(v));
         i += _v.size();
         cout << "Received: " << v.size() << "/" << size << endl;
     }

     return v;
 }

The above call promises you to read 1 byte.
After it completes, where do you start another one?
