this is the open command: open /dev/tty.Mindset-DevB

as you can probably tell, I am a newbie. any help is appreciated.

I am actually having a similar problem. I am trying to get .42.5 working on my box to see if I can program in that version instead of the new one. I think the issue is the new version of PD extended does not include all the flext libraries?* (I think)

I get the object to load, activate the correct COM port and turn the i/o on, but I can not get the open function to work correctly. I know it states that you need to name the correct channel, but the help file lists something that i can not decipher. Is it calling the flext file that has the connection dialogue with the headset? I am also using the USB version neurosky "mind wave". Would it need a different open command?
