I am glad to get your suggestions and comments.
I tested on the same PC and the port was open.

Dear Jie,

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:

 - 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.
 - if it is running on a different computer, be sure to not use
    localhost but the corresponding computer's name or ip
 - 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
 - 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)

I guess you already saw this page (but I thought it'd be wise to
    point to it nonetheless):

I hope that one of these comments help.

Best,
Jörn
