You can use termios to change the behavior of the terminals.

my code is: 

  struct termios options;  fd=open("/dev/ttyS0",O_RDWR );   if(fd==-1)  {printf("Cannot open ttyS0!!\n");  exit(0);  }   fcntl(fd,F_SETFL,0);    tcgetattr(fd,&options);  options.c_cflag |=(CLOCAL | CREAD);//    cfsetispeed(&options,B9600);  cfsetospeed(&options,B9600);   options.c_cflag &= ~PARENB;  options.c_cflag &= ~CSTOPB;  options.c_cflag &= ~CSIZE;  options.c_cflag |= CS8;    //////////////options.c_cflag &= ~CNEW_RTSCTS;  options.c_iflag &= ~(IXON | IXOFF | IXANY);  options.c_iflag = IGNPAR | ICRNL;  options.c_iflag |= INPCK;    options.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG);  options.c_oflag &= ~OPOST;  //options.c_cc[VMIN]=1;  //options.c_cc[VTIME]=0;    tcflush(fd,TCIFLUSH);  tcflush(fd,TCIOFLUSH);    tcsetattr(fd,TCSANOW,&options);    //tcsetattr(1,TCSANOW,&options);  printf("Baudrate 9600 setting OK!!\n");  if (tcsetattr(fd,TCSANOW,&options) != 0)   perror("SetupSerial failure!! \n");
