iirc, on linux at least, [comport] makes pd hang, _whenever_ the other
end disappears. i.e.:

- pulling out the usb-cable, while the arduino is connected
- turning off an rfcomm device

i should test again, if pd hangs immediately, or if only hangs sending
another message/a certain amount of bytes to [comport].
