Hi,

Scenario

[comport] is communicating with an Arduino Nano over USB to control PWM pins.

If [comport] is receiving messages faster than 50 ms Pd will freeze, has to be force quitted, system gets sluggish, and the computer has to be restarted. 

I can replicate it and it happens every time. I wonder if this should be reported as a bug or if it is expected behavior in the specific setting.

Best regards,
Nicklas Lundberg.
