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 

  - 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.
