Posted by GGOOLER on Saturday, December 3, 2011 11:22 PM

just got my loco buffer usb hooked up to my layout and laptop, downloaded wi-throttle for my ipod touch. and now im running my locos wireless thru jmri with the ipod.

got to love when all the stars align and all of this tech stuff works. just had alittle hicup with the jmri and the loco buffer drivers picking com 3 instead of com 4 for some reason. just had to reload the driver and restart the computer and all was fine after the reboot. dont know why the com ports have anything to do with usb ports, but it did for some reason. especially since i can pick any usb port to hook up the loco buffer.

later

The driver for the LocoBuffer (or similar devices, like the PR3 or the NCE USB adapter) create a VCOM port (virtual COM port), and that's how the various software communicates with the device. 

In other words, the driver makes the OS "think" the usb port is a COM port.  That's why proper driver installation is so important with these devices.

 Well, serial ports on PCs have been referred to as COM ports since the dawn of PC time, and USB stands for Universal SERIAL Bus so....

 Now, not everythign plugged in to USB has to be a communications device, so nt everythign gets a COM port. Plug in a memory stick that acts like a drive and it gets - a drive letter. Plug in a printer, it gets a printer port. Hence the universal part - you cna plug in many types of devices, each one gets assigned a virtual port of the type related to the kind of device it is, so a communications device gets a COM port.
