I have installed the bluetooth drivers that came with the dongle( I had to force this because XP loads its own bt drivers and I'd had no success with them and the GPS receiver, which is a FAC BT 30 ). Serial Ports are assigned (you don't seem to be able to choose which com port number). I have paired the device and entered the code. When I try and connect from Memorymap after setting up the program to the serial port assigned I am still unable to receive the data stream from the gps. I know the reciever is working perfectly as everything works fine on an IPAQ 5550.

For a start, make sure you are connecting to the client port. also, make sure you manually connect to the GPS first os your computer will "lean" what port to connect. It will show a dialog telling you what port was assignet (should be the same as the client port).

Now open the program and start using that port. If it's ok, when you use the port the computer will automatically connect to the GPS.

Also, more important, make sure there's no firewall blocking communications. Zone Alarm, Norton and the built-in XP SP2 firewall all can block Bluetooth communications if not properly configured.

Thanks for that. The driver for my serial ports is Widcomm 1.4.1.1 When I look at the client com ports the one assigned is Com 7 but when I go to My Bluetooth Places and look at my GPS set up it will not allow me to select Com 7. If I look in local services com 8 is listed. I have tried all combinations but it still will not work. I do not really understand the difference between local services and client applications. I have disabled power management on the usb hub, set the firewall to allow gps cnnection and still no joy. I also trid with the firewall turned off.
Have you any other ideas? Could it be something in th bios?

The Local Service is a port that will accept connections from other devices. The Client is a port that will connect to other devices.

Since you're running the program on your computer you have to connect to your GPS, and therefore use the Client port.

When you say GPS setup you mean the GPS program on your computer? You shouldn't need to do anything on the GPS itself, only on the program that will use the data coming on this connection to your GPS.

Thankyou once again. I have now rolled back to the generic XPsp2 drivers and had some success. I have been able to receive the data stream from the gps by going to the com port tab on bluetooth devices and selecting add com port. It then detects the device and adds it on the devices tab and it works once. However, if I close the program and restart it it then will not reconnect. I have to go back and delete the device and then go and add the com port again. If I go to the device tab to add the device it says it added it and indicates on the com port tab that ports have been added but never works that way. Is there any wat I can rectify this problem or is it an XP issue?
