How to open & initialize boost::asio::serial_port

boost::asio::io_service io;
// Open serial port
boost::asio::serial_port serial(io, "/dev/ttyUSB0");

// Configure basic serial port parameters: 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));
