Pdreceive opens a socket (with the specified port number) and
waits for messages to arrive from one or more instances of pd(1). Each
message received is printed to the standard output with a trailing semicolon.
The protocol used is easy to implement and is called FUDI.
The port number should agree with the port number of a "netsend" object
within pd. The protocol is "tcp" by default; this does a handshake
guarantee that all messages arrive complete and in their correct order; if you
are sending messages locally or point-to-point you can often get away with
the faster udp protocol instead.
You can also use this to get messages from a Max "pdnetsend" object or even
"pdsend" in another shell. If youre writing another program youre welcome
to just grab the sources for pdsend/pdreceive and adapt them to your own ends;
theyre part of the Pd distribution.
