Identify virtual com port

[rohman]

I am using Labview to recieve barcode scanned from multiple USB scanners connected via virtual com ports.    My plan is to "listen" to multiple com ports and log data as it is recieved by the scanners.  My question is how do I identify which com port each barcode is coming from.

Thank you

As long as they are true serial ports then you will have a unique VISA Resource Name for each (i.e. Com3, Com4). All of the USB scanners that I have used, however, are USB HID devices and appear in windows as a keyboard. Windows device manager and MAX will tell you if they are really serial ports and what names they have.
