Why do my LabView program hang on my PC?

What is the exact string you are writing?

[MarcTUD]

something like that.

Now I tried this... as you can see, the Read Buffer is empty.

[Dennis_Knutson]

You aren't appending a termination character with your write. Look in the manual to see what is required. It should be either a line feed or carriage return. You must right click on the control and select \ Codes Display and use \n or \r.

I dont know exactly what you mean, but i added my program at the attachement... maybe you couldt show me what you mean?

Right-click on your string control and choose '\' Codes Display.  Now put a "\n" at the end of your entered string.

Now there is no error message any more... but the ReadBuffer is still empty.

Furthermore, i can see that the milliseconds multiple has no influence anymore... however what i put in.

[Dennis_Knutson]

You aren't supposed to get any error until you stop the while loop. Have you looked in the manual for the correct termination? Did you try a carriage return? Did you try CR/LF?

[MarcTUD]

After some settings (in aid on your advices) i got as far,

that my buffer shows me the string... but in 3 alternating displays.

Actually only the second display is that what i need.

Can somebody tell me why?

What is the exact model of your instrument?  Whatever you are getting is specified in the user manual of the instrument.
