[PD] ardino "open" message and version

Digging into the [arduino] abstraction I've noticed that it seems to 
assume that [flatspace/comport] will output a "open 1" message when the 
connection is open, but that never happens.

There is a "pd report firmware version" connected to comport's right 
outlet that does the following:

[route open]
[select 1]
[delay 2000]

and that's sent back to [pd command processing], as if that was used to 
ask the arduino for its version when the opening of the connection is 
detected. However, that does never happen because the "open" message 
never comes from comport's right outlet in the first place.

However I do see the firmware version message on the console. So I'm 
guessing that the arduino outputs it when it gets connected, on its own 
initiative, without being asked. Is that right? Or is that triggered 
from somewhere else?

The only thing coming out from flatspace/comport's right outlet seems to 
be a "-1" when the connection is closed.

By the way I now see that the help patch for comport also has a [route 
open] (among other messages) on its right outlet, so maybe it is 
actually a bug in [comport] not outputting the open message?
