DescriptionSets the data available evaluation for this socket.
When new data arrives, this expression is evaluated, so you can call Socket.Read function.
Be aware that expression may be evaluated when just a few bytes are in the read buffer. So the data message you wait for may only be available partly. In that case, please read available bytes, check if whole packet/message arrived and if not, store read data for later and wait for next evaluation.
In the expression the text $$ID$$ will be replaced when evaluated with the socket reference, so you can pass it to other functions if needed.
