-Pdsend sends messages to pd(1), via a socket conection, from pdsend's
+Pdsend sends messages to pd(1), via a socket connection, 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 called FUDI.
