This might be because you try to create a port that already exists on your device. You can use SerialNET.Port.List to get a list of all ports that exists.

On Windows CE/Pocket PC are only COM0 to COM9 available ports, COM10 and above is not possible to create. On desktop Windows COM1 to COM255 are possible to use.

We have a tool to free up COM ports that you don't use on the device. Using this tool you can make an existing port available for usage as a virtual port in SerialTools. More info here:

Hi Johan,

So, can I create multiple bluetooth virtual serial port connection from PDA so that I can create multiple serial connection to device through bluetooth at a same time? It's important caused I need to connect to my embeded device using bluetooth through serial service and then connect to printer using bluetooth through serial service as well.
