Yes, that seems to be a CogVM problem. I tried it now and Cog cannot open the port but an old Squeak4.1 of 17 April 2010 [latest update: #9957] can.

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
