[PD-dev] SIGPIPE on iemnet's tcpserver

[Martin Peach]

Well [udpreceive] should be able to receive from many different senders, 
no? (It's a bug if not...)

Based on what the [udpreceive] receives, route your replies to one or 
more [udpsend]s based on info in the incoming packets, or set the port 
of a single [udpsend] before sending.

UDP is connectionless, it doesn't know or care if the other end exists.
