I have a rather annoying problem with a mouse-gps powered by the
computer and connected to the serial port: The computer sometimes
thinks it is the seral mouse (used for clicking etc).
To get around this I have to manually connect the mouse-gps after the
computer has booted. The system is stationary hidden away in my boat
and not that easy to access.

This is a well known problem in Win2K and XP. The remedy is simple: let the
computer detect the fake mouse and then disconnect the GPS. Go to the device
manager, find the fake mouse and DISABLE it, do not uninstall or remove it.
If you now reboot, you can leave the GPS connected. Another, more expensive
solution is to use one of our NMEA multiplexers with USB interface. The
drivers that come with these multiplexers block any PnP request to it's
virtual serial port, so windows will never find a non-existent mouse.
