[PD] Fwd: Arduino/Raspberry comport issue

The baud rate issue seems strange, as the communicating devices should talk
and listen to the same baud rate...no idea, sorry.

 The baud rate in the arduino code is 9600. But like I said, in pd it
doesn't seem to matter? If the first rate I try in the comport object is
9600 it won't connect. If I change to 115200 it will. Similarly if I close
the patch with 115200 saved and reopen it, the comport won't connect unless
I change the baud rate back to 9600. I haven't tried other speeds but I bet
they would do the same thing. It seems like it wants to do the opposite of
what I want it to do. A mind of its own.

 I have a message going to the comport object to open it. Either [open 0
9600( with whatever port [devices] tells me, or [devicename /dev/ttyAMA0

  Are you sure the baud rate you set to [comport] is the same as the code
you load on your Arduino? That could be a problem..
 If you send the [devices( message to [comport] what do you get in the
