Can the carriage return within a variant be read as the terminatio​n condition for VISA READ?

Question

Hi guys, I am trying to read a variant data using VISA READ. The VISA READ is set to terminate reading when it sees a carriage return.
Is there a chance that for the CR "encapsulated" within the variant be read by the VISA READ, and cause it to terminate?
Cheers!

Since with the Flatten to String you are basically sending a binary representation of the data, you are going to have problems if you have the termination character enabled since byte 13 would be part of perfectly valid data and not just represent the end of a transmission.
What you might want to do is disable the termination character.  Of course now you don't know how many bytes to read.  So prepend your message to write with the number of bytes that are a part of the message (string length).  You may want to use two bytes, (one byte would only give you messages up to 255 characters in length.)
Now on your reading end, read 2 bytes, convert them to a number and feed that number in the next VISA read which will then read that many bytes.
For examples, look at the TCP/IP read write examples in the example finder and you'll see how they send a message with 4 bytes to tell how much data makes up the rest of the message.
