Something is unclear to me.
I'm on linux, with command line, my path to pd-gui is /usr/local/lib/pd/tcl/pd-gui.tcl
So the message is " vis /usr/local/lib/pd/tcl/pd-gui.tcl "
In order to send this to pd,
Should I use 'pdsend' and create a netreceive in my patch ?
( this worked fine)
Or find the port "pd" already opened ?
