How do I use IB(Mac) to display text from opened tty port?

Question

I'm using OSX10.9.4, XCode 5.1.1 etc, Mac Mini. 2012. 16GB. Fast processor.
I can open the serial/usb port and read the data from it with a [command line] tool...
sample code here.
What I'd like to be able to do is display the data that comes in live in a Graphical Interface, not as a command line tool. It also saves it to a file, and perhaps it's easier to read the continuously built file? Certainly for building historical data.
[code]
#ifdef DEBUG
    printf("Debug Mode on\n");
#endif
  fd = open(PORT, O_RDWR );
#ifdef DEBUG
  printf("...Serial port open - Return code : %d\n", fd);
#endif
  if (-1 == fd)
        perror(PORT); perror(msg); exit(-1);
  struct termios theTermios;
  memset(&theTermios, 0, sizeof(struct termios));
  cfmakeraw(&theTermios);
  cfsetspeed(&theTermios, 38400);
  theTermios.c_cflag = CREAD | CLOCAL; // turn on READ and ignore modem control lines
  theTermios.c_cflag |= CS8;
  theTermios.c_cc[VMIN] = 1;
  theTermios.c_cc[VTIME] = 0; // set to 10 if 1 sec timeout
  ret = ioctl(fd, TIOCSETA, &theTermios);
#ifdef DEBUG
  printf("opening /dev/cu.usbserial...\n");
#endif
  fd = open("/dev/cu.usbmodem14311", O_RDONLY);
#ifdef DEBUG
  printf("...Serial port open - Return code : %d\n", fd);
#endif
  if (fd < 0)
  printf("Erreur a l'ouverture de /dev/cu.usbserial - Code=%d\n", fd);
  exit(1);
#ifdef DEBUG
  printf("Serial port opened...\n");
#endif
    /* while (1) is an endless loop, unless errors develop */
    pFile=fopen(DATASTORE,"wt");
  while (1)
  ret = read(fd, &c, 1);
  if (ret == 1) {
        /*  put the incoming data into an array/structure */
[/code]
Thanks

Answer 1

you can do this with the firewall (ipfw) or ssh. id suggest googling those and also posting this in the UNIX forum here. Ive never attempted to do it but i know it can be done with either. which you use will depend on what you need to accomplish.
