You are not sending the carriage return line code. The correct code is \r not /r like you have and in order to send it correctly, you have to right click on the string constant and select '\' Code Display. Otherwise, you are just sending the characters '\' and 'r'. The shipping example called Basic Serial Write and Read has a front panel control that is set correctly. You can also look at the advanced example to see how to set the write termination character with a VISA property node.
