I've been reading about the implications of the Diecimila's Automatic (Software) Reset feature here; http://www.arduino.cc/en/Main/ArduinoBoardDiecimila it says "If a sketch running on the board receives one-time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data" would this apply to Pd?

Thanks
