Connecting a GPS to Laptop

Wrong port there mate. Take it to the electronics shop just to be 100% but I have looked at that end of enough laptops to know that I have never seen a DB25 connector on the back that was for serial. If is is female 25 pins it is for the parallel printer. There are USB convertors on the market however a few things to note for OziExplorer use: Keep the baud rate down a little say 19200 or 9600 (you do not need it any faster anyway) - reason is the USB - Serial converters do not support standard comm port interupt driven flow control and you can get overruns. USB cables do fall out (there is no fixings for the connection), ensure the plug will not fall out over the bumps. When you plug in the USB convertor take note of the com port it is assigned as you will need this in OziExplorer (it is not always com1).

Good luck and have fun.
