    Dear Jie,<br>
    <br>
    I'm afraid I cannot really help you with your particular problem,
    but some basics that you should generally be covered and may thus
    help nonetheless:<br>
    <br>
     - when using cfg.dataset = '(...) localhost (...) ' make sure that
    the shared memory/buffer is running locally, i.e. on the same
    computer. This involves starting tmsi2ft on that computer.<br>
     - if it is running on a different computer, be sure to not use
    localhost but the corresponding computer's name or ip<br>
     - make sure that the port (here 1972) is open (i.e. not blocked by
    some firewall or in use by another program) and that the buffer
    accesses it<br>
     - maybe you could try to 'ping' the ip where the buffer is supposed
    to run to check whether everything is set up correctly (not sure if
    this actually works)<br>
    <br>
    I guess you already saw this page (but I thought it'd be wise to
    point to it nonetheless):<br>

    <br>
    I hope that one of these comments help.<br>
    <br>
    Best,<br>
