AppleTalk Node
The AppleTalk Echo Protocol (AEP) sends a datagram (an Echo Request)
from one node to another. The destination node returns, or echoes, the
datagram to the sender (using an Echo Reply). This process allows you to
determine whether or not a node is accessible before starting a session.
