Paradigm not sending or receiving UDP

Hi all.

Is there a trick to getting Paradigm to send and receive my UDP strings?

I have some macros that should be sending UDP messages around the system but cannot see them on wireshark and the Rx device isnt seeing them either.  I can mimic the commands on the net using a UDP client and all good.

I also have some UDP trigger strings defined in the serial input handler but once again, no joy.

My system is an ACP in an ERn rack with 1x 7" touch screen (and some other stuff).  All reports no faults and green in light designer (2.1.2.9.0.782).

I think its just not doing the UDP side.

Thanks a lot - Jim
