Thank you Martin, Miller,
please excuse me, I mixed things up when asking. I wanted to know what the outlet of netSEND really indicates. Ups, sorry!
So rephrased:
Does it indicate whether Pd was able to open a port through the OS?
Does it indicate whether a (TCP) packet actually arrived at the receiver?
Does it indicate whether the connection is "alive" (whatever that means)?
Miller, you are right, netsend does not report when a connection got closed, hence my above questions.
best, P

The right outlet indicates that the port is open and the other end is listening.
or does it indicate if a TCP packet arrived at the destination?
And: Am I correct assuming that netsend only outputs a message when it got a (send ...) message into its inlet? So there is no way to indicate whether the receiving machine is online unless I keep sending heartbeat/ping messages?
If the other end drops the connection, then the right outlet will output zero, but it might not happen right away. Especially with wireless it's better to have some kind of heartbeat ping-pong going at a higher level than the OS.
