hello list!

i'm trying to get my arduino board to run with pd. 
i work on a g4 powerbook, OS 10.4.8 with the latest installer from hans, Pd-0.39.2-extended-test7.

the arduino works fine with processing, the blinking led test file works, so i upload the pd_firmware.

when i open the arduino-help file everything seems to work fine, i can open a connection and get this message:
[comport] opened serial line device 1 (/dev/tty.Bluetooth-PDA-Sync)
 - is this already wrong? is that the correct type of connection?

then i set the port 13 to output and toggle the pin 13 on and off, but the led just doesn't start to blink.

i'm sorry if this is a complete newbie error, but still - any recommendations?

thank you in advance,

emanuel
