yes i changed the VI by looking at the  @crossrulz`s video but the result is same. Can you please tell me what is the problem?

Honestly not without the device you are communicating with. I gather you programmed the microcontroller?

yes im sending command to the micro controller and receiving output back from it and no i did not send send a \n or \r at the end of data string.Do i have to use both \n or \r or any single?

Well your termination character your microcontroller is sending has to match what your LabVIEW program is expecting or your LabVIEW program has to expect what your microcontroller is sending...

The default is a single Carriage Return.

yes im sending command to the already programmed  micro controller and receiving output back from it which is working fine with putty (sending command and receiving exact output which i need ) and no i did not send send a \n or \r at the end of data string.

And it's more than just putting  \ before an n or r it has to be the proper ASCII character

yes those are ascii chars. I will try with \n and  \r and i will get back

hi everyone,

the problem solved. i inserted delay before read and also in delay in while loop because i was reading too fast. 

Thank you
