Subroutine Missing return node information

That's not easy, as this is a OWN bus (Legrand) and you can't replicate on your own.
But take that message: *#*1##*#*1##*#18*74#0*113*0##*#*1##
I don't need to extract ALL of the messages, but just *#18*74#0*113*0##, discarding the rest. But this central message can vary, depending on the input in the subroutine.
