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