Arduino to Flash

Firstly, please excuse my ignorance, I'm really not very knowledgeable on this...

Im trying to get my Arduino board to send its sensor data to a flash application (which is actually within a browser window)

I have uploaded arduino_flash.pde to my board without problems, and I know the board and sensors are definitely working fine.

I then edit my serproxy.cfg file to the serial port that the Arduino software says Im using.

I run serproxy with Terminal and get the 'waiting for client' message, then when I open the swf in either flash player or Safari I get the message 'Failed to open comm port - connection refused'.

I have changed the security settings to accept my files, and also do not have the Arduino software open when Im trying this.

I think what the problem possibly is is that I dont know which ports relate to which numbers on my laptop. The Arduino software doesnt tell me what 'com port' im using, only the 'serial port'. How do I find out which port I have my board plugged into?

Many thanks

It helps when asking questions like this to state what operating system you are using. Since you mention Safari, I presume you're using a Mac?
