[PD] Another arduino weirdness

[Matteo Sisti Sette]

Hi,

With this:

[arduino]
        |
       [print ARDUINO]

On Linux, when I open the connection, it prints:
ARDUINO: version 2 2
ARDUINO: StandardFirmata_2_2_forUNO_0_3 2 2
ARDUINO: firmware StandardFirmata_2_2_forUNO_0_3 2 2

On Windows (with the very same arduino board), it doesn't print anything!!

Yet everything else works and I do get the data messages from the left 
inlet of arduino!

How can that be????
