[CM] How to send udp bundles from Grace on Linux?

[Forrest Curo]

Tito:
Csound simply runs & ends from your command line. Just runs out of score
events & stops.

It prefers:
csound -odac -+rtaudio=null *--daemon* -L "score"  --orc test.orc

I know that  -L is supposed to imply running in '--daemon' mode but maybe
not when using an .orc file?

No problem, thanks!
