Connecting i-Mat Pocket PC with Bluetooth receiver

Hi all,
I have an I-Mate Pocket PC with Bluetooth ports COM4,COM5.
Also I have two external devices a GPS receiver,Printer.
The two devices can connect the Pocket with Bluetooth connection.
I built a small application in VS.Net 2003 to read data from the GPS receiver, and to write these data to the printer.
I defined the Pocket recognize the GPS and the Receiver automaticlly.
The problem is that the application cann't use the two devices on the same two ports 4,5.
Is what I did right? How I have to do that?
What can be the Problem? I can I define each device on different virtual port, maybe this is the problwem.

Please help .
Best regards...

What is the error you are seeing? Can you post the part of code that is erroring out?

You might have more success posting in the Smart devices: General forum. This one has posts about the device emulator.
