TCP- basic question

[fgrootent]

Hoi,

With you're program is nothing wrong.

May you should take a look at the cllient server examples. 

Probably the server (laboratory equipment) is not running.

Is it possible to verify if the server is running on the laboratory equipment? if so you should check this.

furthurmore you should check tcp/ip settings on you're operating system if it is possible receive and send

messages over tcp/ip (firewall settings, etc)

Hi Fred,

Thanks for your reply, it was very useful.

Finally I could communicated  with laboratory equipment using TCP/IP connection. The problem was in the remote port, I changed  4444 port by 300 port, and changed (Tools-->Options -->VI server) too. I checked Firewall and I turned it off ,and  now the program works fine!!

Thank you very much.

Regards.
