    Do all/most USB gps devices create a virtual com port?

    I'm considering getting a new GPS to dedicate to the car computer, but I would like to use the comport duplication software I recently got working. Do the USB devices work by creating a comport for the map software to talk to, or does the modern stuff just know how to talk straight to usb? If the USB doesn't create a comport, I'll still with a serial port device to increase my chances of being able to split the signal through software...

    I think it mostly depends on the software, not the gps hardware. Street Atlas has built-in support for the Earthmate and can talk directly to the Earthmate over usb, but using it with Mappoint requires you to load the usb-serial driver because it's looking for a comm port. That's probably true for most other software as well.

    ya like the earthmate installer will ask you if you want to use the gps for other apps .. if you select that option it'll create the virtual com port
