Hi Everybody.

I'm just started with Pharo, and Arduino. And i like to comunicate both.  I
instaled the package sent by Ricardo Moran in a Pharo 1.4 with the Cogvm
from the Jenkins server, but i can't make the serials port works. The
Arduino board, i have, is connected to usb, wich ubuntu detects as
/dev/ttyACM0.

I tried opening serial ports, like this:

sp:=SerialPort new.
sp openPort: '/dev/ttyACM0'.

sp openPort: 'ttyACM0'.

sp openPort: 'ACM0'.

sp openPort: '/ttyACM0'.

But all they fail with a error saying ""Cannot  open..."
After that, i have also, tried this:

(1 to: 10000) select:[:port | [SerialPort new openPort:port;close. true]
on:Error do: [false]]

and had a empty collection.

And also tried giving full permissions to the port and executed the vm
sudoed...

Are serial ports working on ubuntu?. Do i have to download a special vm?.
(I would like to do a demo of arduino on monday, at work, and i would like
to do in Pharo.)

Cheers,
Mariano
