Hi,
First of all... I noticed that there is a VISA Close.vi in frame 0, and therefore, VISA Read (in frame 1) will not be functional.
Also, you may wanna consider place the VISA Configure Serial Port.vi outside just before entering the while-loop. Place a VISA Close only after exiting the while-loop.
Please add a small loop-delay (say 100ms) within the while-loop to free up the CPU.
Last but not least, beware of the interval which could be of necessary between the write and read.
Cheers!
