That is one of the many cases where my advice would be : don't use 
firmata/pduino. Program the arduino for real. Use a basic custom 
protocol over the serial link, and talk to the arduino with [comport]. 
You'd spend much more time trying to get it to work with firmata/pduino 
than programming the 'duino and let it do the real work instead of 
clogging your serial port.
