: When plugging in the GPS to the serial port, the mouse starts running all over the screen, randomly clicking things! Answer: The operating system has mistaken the GPS for a serial mouse. Disable the serial mouse (normally in the device manager - don't delete it, set it to disabled).
: I want to use it to feed more than one application simultaneously. Is that possible? Answer: Yes. GPS is addicting and once you start being able to pinpoint your location, you start to collect applications that do various things with GPS and require simultaneous access to your unit. Unfortunately, if your GPS is serial, you can't share the com port between two applications like iGuidance
and Netstumbler. Fortunately, there are a few solutions for this.
* Some Bluetooth
receivers permit more than one connection at a time.
is a commercial application that allows you to share your ports with more than one application. It has a 14 day trial download.

, also allows you to share access to your GPS.
can act as a server to GPS applications, allowing more than one application to read from the GPS data stream at a time. Unfortunately, each application that needs GPS information must be GPSD
aware or you need to use virtual serial ports such as the one fromHW
, and you may need to send the "R" character to the virtual serial port pointed to gpsd (typically 127.0.0.1, port 2947) to turn on the "Raw" NMEA data
stream, but this can be done in a command window with "ECHO R >COMxx".
