Hello folks,
If I am attempting to communicate with an external device such as a GPS (driver installed) and it shows up as a COM port on my computer even though it is hooked up via USB on the xPC target, can I still use the RS232 library from xPC target to read/write to the device?
Thank you, Rob

USB virtual serial ports require a device driver in order to communicated with as serial ports. If your xPC includes the appropriate device driver then you can use the RS232 library.
I know that some USB support is being offered on xPC now, but I have not examined the documentation to find out whether USB serial ports are one of them.

You are correct, I overlooked this fact. It looks like a virtual com port via USB is out of the question at the moment since I have little time to create a driver so I will resort to sending my GPS coordinates to an external micro-controller which will then be connected via RS232 to the target PC.
