Hello Every one....

  Iam hardly struggling about an error of -1073807339...i have attatced a image of my error vi....problem is accuring at READ VI...

     Plese help me to solve...

[Ranjeet_Singh]

Need more details..

how many bytes you are reading (1024) in that case are you able to read complete data?

[hanumeshbujji]

no sir i can't able to read data due to error...but in hyper terminal iam getting data... 

[Ranjeet_Singh]

First close hyperterminal and try only from labview application.. In that case use highlight.. use proper com port. is com port showing in labview i.e from visa resource view?

When reading from LV ensure data is avaible on buffer i.e other device is sending the data

[hanumeshbujji]

yes sir other device is sending data..and com port is showing...or plsese attach a serial data read vi....

Check this.

Ensure same baud rate, proper com port selection and enter number of byte before running the application
