Service Creation +WIPCREATE

9.4.1.1. Description
The +WIPCREATE command is used to create UDP, TCP client and TCP server sockets associated
with the specified index.
If a local port is specified while creating a socket, the created socket will be assigned to this port; if
not, a port will be assigned dynamically by the firmware application. If peer IP and peer port is
specified, the created socket will be connected to the specified IP and port.
The TCP server cannot be used to transfer data. To transfer data, it creates a local TCP client socket.
using spawning, the socket passively listens on a specified port for incoming connections. The
diagram below shows the different states managed for a TCP server.
