I need some help with communcating with the serial port. I tried using the Hyperterminal and at first it said that my port was busy. I didn't think it was, but then I noticed that the power on the device that hooks up to it was turned on. When I turned the power off, I was able to connect. I can't run my program with the power off, so now what do I do? I need some help configuring the VISA. Can someone please help me?
