It's strange the [print] doesn't display the quotes if they are present in the output of [route].
Can you add a [print income] after [netreceive] in order we see if the message is clear?

FYI this patch works great

It works perfectly with this test:

writesf-test.pd

For fun this is the cross product

I don't think you will be able to protect any patch that you sell....!

Maybe it's possible with compilation, PlugData is able to do this : https://plugdata.org/docs/book/CompilingPatches.html

See [vline~] help file

Another possibility is to let the abstraction take configuration message.

DO NOT split event flow without a trigger !

Is there a way to send a number from a bang using Send symbol in Bang Properties?

No, a bang send bangs.
The symbol entered is not interpreted (but $0 is replaced by the patch id).
