Feb 5, 2015 - If you read the tutorial it explains how that code works, but here's a sample. (In the tutorial, they are doing a WPF app, which is slightly different from Windows Forms in how the controls are defined, but the code is basically the same). This is an event of the serial port - you respond to the event by displaying. Now I know in Labview I have to read serial data from COM 4. 3) For the arduino side. Extract the temp digits, display the value and graph the data.

Hello, I'm using VISA serial communication in my vi to communicate with hardware. My laptop has two COM ports COM1 and COM2.

I will be using VISA configure serial port to set particular Com Port. COM port will be indicated using VISA resource name.

I should know the com status before other operation is done. I.e say I have selected com2 in resource name while configuring COM port, but I have connected serial cable from hardware to COM1.How can I know the difference?? I tried checking the error line,but unfortunately its not giving any error since COM1 is present in laptop. Thanking you, sushmith.
