I don't understand what that gets you over just a batch file or other scripting language that calls the command you built at line 72, but I don't really know what I'm looking at. if this works for you, groovy! If you're making this to share with others, please use "GPSBabel" (no space, capital B) for consistency. You may (or may not) find https://www.gpsbabel.org/htmldoc-development/fmt_skytraq.html helpful. I can't remember the details of the skytraq, but it's entirely possible that you really can't authoritatively enumerate the devices. (It may be possible to do it "well enough" if you have some control over the hardware tree.) Lots of these logger products just use a commodity USB/TTL chip internally to plumb the GPS+Processor's TTL serial out to the USB Bus. They thus tend to have USB IDs of that chip (Prolific, FTDI, et.) and not of the actual GPS device. So your system may know you have a "COM6:" out there, but not know if COM6: is this GPS or if it's a USB missile rocket launcher or other whatever. If it's a home/personal system that you control, that may not matter much. Good luck in your project. On Tue, Sep 12, 2017 at 7:59 PM, Josh De La Rosa <jos...@gm...> wrote: > Thanks for the feedback.
