 From looking at the code it only sends the digital pins on startup, not 
the version. Probably it's the Pd patch that asks for the version.

that might depend on the driver for the FTDI chip, which is different 
from a regular USB serial connection. You might want to try a teensy 
instead of an arduino as it uses standard USB serial protocol.
