Q: arduino serial problem

I've got an Arduino Uno connected to my USB port on a new Map Book Pro running the latest Snow Leopard.   The Arduino is running a little program that sends analog output to the Mac.  I can see the data on the serial monitor.  However, if I type

 

/dev/tty.* T

 

in Terminal, I've read that I should see a list of serial ports, including the one that the Arduino is connected to, but all I get is

 

-bash: /dev/tty.Bluetooth-Modem: Permission denied

 

which is my cable modem (I think).... or is it? In any case, that doesn't match the serial port name the monitor is displaying.   Any idea what the problem is?

Powerbook G4, Mac OS X (10.3.x)

    I have three arduino Uno boards, a Make: brand a genuine Arduino Uno and a 3rd party R3.

     

    After spending a solid week of my precious free time going through at least 30 different solutions trying to install /dev/tty.usbmodemXXXX The best I was able to do was program 'blink' with /dev/cu.usbmodem. Any other program fails miserably.

     

    I finally solved the problem. I bought a cheap PC to program the Arduino. Thanks Apple!!     /<sarcasm>
