pdsend - send messages to pd on this or a remote machine
pdsend port-number [hostname] [udp|tcp]
Pdsend sends messages to pd(1), via a socket conection, from pdsend's
standard input. This input can be any stream of Pd messages separated
by semicolons. This is probably the easiest way to control pd from
another application. The protocol used is easy to implement and is
The port number should agree with the port number of a "netreceive"
object within pd. The hostname is "localhost" by default and can be a
domain name or an IP address. The protocol is "tcp" by default; this
does a handshake to 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 talk to a Max "pdnetreceive" object or even
just a "pdreceive" in another shell. If you're writing another program
you're welcome to just grab the sources for pdsend/pdreceive and adapt
them to your own ends; they're part of the Pd distribution.
