I have already written a subVI for reading and parsing the output of a Alicat Scientific MFC (16 series), which works great, however I am having some difficulty sending a setpoint to the MFC. I have attached a test subVI that I am writing. All of the com settings are matched to the MFC as well (19200 baud, 8 data bits, no parity, 1 stop bit, no flow control). After setting the proper resource channel, I input the following into the buffer field:
\r\r\r\r\r\r\r32000\r
which I believe should send the setpoint value to the MFC, however I am seing no response. When I input the same string into the VISA test panel in MAX, it works however. Anybody have an idea on what I am doing wrong? Please also let me know if there is any additional information that I could supply that would be helpful. Thank you.

You are sending the characters '\' and 'r', not a carriage return.
Set the write buffer string control to '\' Codes Display in order to send '\' Codes correctly. It's a simple right click.
