Is there an option in octave to listen to this specific port and get
triggered when data is transferred. I also think that avoiding a loop is
better?

There's even a way of doing what you want by calling an external network listener from your .m code:

   system("nc -l localhost 8080")

will sit there waiting until the netcat (nc) program returns, which will happen when you connect to localhost:8080; you can test that by executing

   echo test | nc localhost 8080

from another terminal. 'nc -l'  opens a socket in a listening mode and does a select() on it;  as others have pointed out, you can write an equivalent code in your .oct file.
