Thank you very much for your reply,

here I am attaching my Vi ,and screen shot of my Vi and as well Screen shot of the software which I am using.

Now the thing is that I have made Vi in order to check the connectivity of RS232 with the instrument,means when RS232 is connected then LED will be ON and when RS232 is not connected Then LED will be OFF.

But I got the problem that even when I have not connected RS232 with instrument even though i didn't get any error and also same with com port what ever comport I give but its not generate any error.

Even I tried with by removing com port also but still my vi not generate any error means every time LED is ON.

So will you please tell me that what should I do in order to solve this problem,should I make My Vi by using VISA library and then try to run??

Form where should I start?

And will you please let me know is there any other information you need??

And will you please tell me about how to create string in order to find query??

Thanks a lot....

First of all, the parameters in one pic don't match with the params in the other.  (Check out the parity and stop/start.)  Once you get that straightened out, maybe everything else will follow...

Hello Billko,

i made all parameters same and then i tried again but still i got same problem....

Thanks for reply..

[billko]

They may match... but are they right?

Thank you very much for reply....

May be yes because in my software ,there is option regarding to port setting and in that port configuration is given same, if I change the setting  then my software is not connected with RS232,so I think its right.

And its same in my  device and manager in my computer where we can see then port setting...

Or will you please tell me that is there other way to check the configuration of that....

Thank you ..Again....

We are missing something VERY basic here, because this should be a no-brainer...

Maybe a diagram of the H/W configuration, including PC or PCs.
