如何通过boost::asio和shared_ptr创建串口

#include <boost/asio.hpp>
#include <boost/shared_ptr.hpp>
#include <boost/make_shared.hpp>

boost::asio::io_service io_service;
boost::shared_ptr<boost::asio::serial_port> serial_port = boost::make_shared<boost::asio::serial_port>(io_service);

serial_port->open("/dev/ttyUSB0");  // 串口设备路径
serial_port->set_option(boost::asio::serial_port_base::baud_rate(9600));  // 波特率
serial_port->set_option(boost::asio::serial_port_base::character_size(8));  // 数据位
serial_port->set_option(boost::asio::serial_port_base::parity(boost::asio::serial_port_base::parity::none));  // 校验位
serial_port->set_option(boost::asio::serial_port_base::stop_bits(boost::asio::serial_port_base::stop_bits::one));  // 停止位

boost::array<char, 128> read_buffer;  // 读缓冲区
std::string write_data = "Hello, Serial Port!";  // 写缓冲区

void read_handler(const boost::system::error_code& error, std::size_t bytes_transferred) {
    if (!error) {
        // 处理读取到的数据
        std::cout << "Received: " << std::string(read_buffer.data(), bytes_transferred) << std::endl;
    } else {
        // 处理读取错误
        std::cout << "Read error: " << error.message() << std::endl;
    }
}

void write_handler(const boost::system::error_code& error, std::size_t bytes_transferred) {
    if (!error) {
        // 写入成功
        std::cout << "Write success!" << std::endl;
    } else {
        // 写入错误
        std::cout << "Write error: " << error.message() << std::endl;
    }
}

serial_port->async_read_some(boost::asio::buffer(read_buffer), read_handler);
serial_port->async_write_some(boost::asio::buffer(write_data), write_handler);
