如何打开和初始化 boost::asio::serial_port

boost::asio::io_service io;
// 打开串口
boost::asio::serial_port serial(io, "/dev/ttyUSB0");

// 配置基本串口参数：115.2kBaud, 8N1
serial.set_option(boost::asio::serial_port_base::baud_rate(115200));
serial.set_option(boost::asio::serial_port_base::character_size(8 /* data bits */));
serial.set_option(boost::asio::serial_port_base::parity(boost::asio::serial_port_base::parity::none));
serial.set_option(boost::asio::serial_port_base::stop_bits(boost::asio::serial_port_base::stop_bits::one));
