Thanks for the help again. I'll look into the terminal emulation program...I'm new in LabView so please bear with me while I'm trying to understand these terms. Everything worked and everything is the same, the only thing that changed was that it kept giving me the same error when I was running TestLoops.vi step by step via 'Highlight Execution'. The motor will still move if I ignore the error but it stops and gives me the error at every Serial Communication Port in my TestLoops.vi so I obviously need to get it fixed. Thanks.
I didn't notice you 'p.s.' until now. I had known that the execute button does nothing and was trying to think of a solution where it doesn't run until I hit the 'Execute'. Do I need to put that in a loop of sorts in order to run it the way I want?
'In your subVI, you also reconfigure the serial port and close it.' I'm not quite understanding this but I'll take a look around and see what info I can find online. Thanks.
