Sir,
Thank you so much for the reply.
Sorry for disturbing you again.Let me explain more about my problem.
The data is residing in a seral device(modem) which is connected to the PC.
I want to display the data from the serial device on the monitor of the same PC.
So far i was fully involved in plotting graphs.So i dont have any idea about my current problem.
Is it achievable in an easy and efficient manner?
(Actually i dont want to link it with the database as the system now is perfect in sending data to the database
only problem is with the real time display.)
Thanks once again...

I'm not sure exatly what you are asking about. Is it just how to read data from a serial device? If so, then I would suggest you look at the shipping examples. There is one called Basic Serial Write and Read and one called Advanced Serial Write and Read. Data is returned with a VISA Read in string format and then you can convert that for display on a chart. It sounds like a chart would suit your purpose of plotting as data is acquired.
If you could provide some more details on what the device is and how it sends data, more specific help can be provided. Have you already been able to communicate to the device with something like Hyperterminal?
