&par Example Description

This example shows how to create TCP server. received and send data to TCP Client
by tcp assisatant.

 phenomenon :
  - After initialization, You can see the system information on serial assisatant through USART1 or LCD screen.
  - create server(IP 192.168.73.22:5000) by KEY1. And close server by KEY2.
  - you can connect and send data to the EVAL board by tcp assisatant.

&par Hardware Description

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled
