    options.c_cflag &= ~PARENB;
    options.c_cflag &= ~CSTOPB;
    options.c_cflag &= ~CSIZE;
    options.c_cflag |= CS8;

    options.c_iflag &= ~(IXON | IXOFF | IXANY);
    options.c_iflag &= ~(INLCR | IGNCR | ICRNL);
    options.c_oflag &= ~OPOST;

    options.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG);
