I am making my final year project and using Labview for it. I have to make RS232 serial communication with my PC but when I open my project application it shows many com ports like  COM1 ,COM2 , LPT and etc but I don’t know which one is my serial port, so that I can communicate.

Is there any software or any method to verify which port I am using?

Hi Jeniffer,

Yes, you can find two serial ports which is COM1 and COM2 and one parallel port /LPT in old motherboards. LTP port is for printers with parallel connector. So you can use either COM1 or COM2 ports for you to attach your RS232 connector. And the procedure to check which serial ports you are using, you can check it through Device Manager. LhenP

Check the BIOS to be sure that the 2 different Com ports are enabled. The prog. should have a means to select one or the other. If one doesn't work the other's bound to. Serial port drivers are supplied by the OS. Any special drivers should be supplied by the vendor.
