  "Causes the system to create a socket to listen on LISTEN-PORT.
TRANSPORT-PROTOCOL may be either :TCP or :UDP for stream and datagram oriented services respectively.
When somebody connects to this port a process is created in which the TOPLEVEL-FUNCTION is called
on a stream connected to the active socket.
The stream and socket are automatically closed when the function exits.
If AUTO-ENABLE? is non-NIL, this server will enabled by calls to (enable-all-network-services),
which is run whenever TCP is initialized."
