While we're at it, it seems [netreceive] (in TCP mode) can only send
back to all connected clients, but not to a specific one. 
Actually, a [sendto( message for [netreceive] would already allow you to build a fully functional UDP server in Pd vanilla.

BTW, there is a [udpserver] object in iemnet, but it's not really usable yet (it only allows to send messages to the last sender).

Hey all

I would like to open a datagram listening socket and be able to send
back to clients from which I received messages. It seems both [netsend
-u] and (obviously) [netreceive -u] actually can open a listening
socket. However, [netreceive -u] can't send anything back. While
[netsend -u] can send messages back, it doesn't show the source address
of the incoming packets. And using [netreceive -u] for receiving and
[netsend -u] for sending back doesn't work, because for the packets to
arrive at the client, they need to be sent from the same port that is
already occupied by [netreceive]. 

Yet, as long as I used TCP and iemnet, this was possible. However, as
far as I can tell, it's not possible with UDP, neither with iemnet nor
with Pd's built-in classes.

Is that something worth to make a feature request for?
