Check connected tcp ports

What about using storage to send command?
in you resident script you read a table in storage and send all element you read, and in your event script you write all your command

This way you have a FIFO and can send multiple command at a time:
On, switch to channel X, volume Y, ....

I've tested in the past this solution but storage is not so fast as must be.
