Hi boost users

I'm a newbie to boost trying to use a serial port as an iostream.
While searching the archives I found a post by Rob Desbois (2008-01-18
13:02) trying to achive the same. Unfortunately the solution wasn't
posted.

This is what I got so far:

#include <boost/asio.hpp>
#include <boost/iostreams/stream.hpp>

class serial_device
{
public:
        typedef char char_type;
        typedef boost::iostreams::bidirectional_device_tag category;

        serial_device(boost::asio::io_service& io_service, const std::string&
port, int baudrate = 9600) :
                serial_port(io_service, port)
        {
                typedef boost::asio::serial_port_base spb;
                serial_port.set_option(spb::baud_rate(baudrate));
        };

        std::streamsize read(char* buf, std::streamsize n)
        {
                boost::asio::read(serial_port, boost::asio::buffer(buf, n));
        }

        std::streamsize write(const char* buf, std::streamsize n)
        {
                boost::asio::write(serial_port, boost::asio::buffer(buf, n));
        }

private:
        boost::asio::serial_port serial_port;
};

int main(void)
{
        boost::asio::io_service io_service;
        serial_device serial(io_service, "/dev/ttyS0", 115200);

        //boost::iostreams::stream<serial_device> s(serial);
}

If I uncomment the last line it fails to compile:

Could anyone please explain what I'm doing wrong?

Thanks,
