[PD] port used by sendOSC

[Axel Balley]

Hi all !
I'm new to pd and to this list, and I'm currently trying to learn how  
to make SuperCollider3 and pd interact with each other.
I can send messages to the SC server from pd using the sendOSC  
object, however I need to know which port is used to send the  
messages, so I can configure the dumpOSC object to display the SC  
server's replies.

Can anyone help ?

Thanks in advance
