    這里向用(yong)戶介紹一個(ge)讓(rang)ZLIP同時處理4個(ge)TCP連(lian)接（2個(ge)客戶端、2個(ge)服務(wu)器端）、兩個(ge)UDP連(lian)接和PING的(de)程序。該演(yan)示將讓(rang)用(yong)戶初步了(le)解ZLIP的(de)功能(neng)。

   按照開發運行新程序一節的(de)步驟(zou)將UseZLIPLib下載(zai)到開發板中。

1． 打開sscomv2.0，波特率為19200；重新打開開發板電源，串口顯示：

test_complex_send_recv test...
TODO: listen at 192.168.0.3:1024, and press key
press any key...

按以上要求讓SocketTestDlg在TCP1024端口監聽，然后向串口發送一個任意字符，作為“press key”。

串口和SocketTestDlg提示信息表明開發板向PC機發起了兩個連接并建立了兩個連接。
2． 發送文件：由于發送文件需要較長時間，需要再運行一個SocketTestDlg程序，并使用Client Connect向192.168.0.2:1024發起連接。

串口輸出和SocketTestDlg提示信息表明連接建立。SocketTestDlg中的send file選擇為“\工具\SocketTestDlg\send_test_file\1_75M”，Send Mode選擇Send File。點擊ClientSend 開始發送文件。
3． 采用ping 192.168.0.2 –t，PING開發板。

4． 做如下的操作（為了演示ZLIP的同時處理多個連接的能力，以下操作在上面的數據發送和PING同時進行）：
(1) 采用ServerSend向板子發送“a”字符，串口顯示“sc0 a”和“sc1 a”表明板子上的兩個TCP客戶端都收到數據“a”。

(2) 采用ClienConnect向板子的192.168.0.2:1024發起連接，可建立連接。串口顯示“lisen 1 accept”，表明連接建立。連接建立以后采用ClientSend發送“b”，服務器端將收到回饋數據“b”。
(3) SocketTestDlg創建UDP后，向UDP 192.168.0.2:1024和UDP 192.168.0.2:1025分別發送“c和發送“d”字符，串口顯示“su0 recv2:c”和“su1 recv2:d”表明板子上的兩個UDP實例也收到了數據。
5． 當第二步“發送文件”完成后，點擊ClientClose關閉連接，此時串口和SocketTestDlg提示消息如下：

圖中顯示了接收方（串口顯示的數據）和發送方（SocketTestDlg顯示的數據）的數據校驗和一致，表明發送數據無誤。
在該演示例子中，演示了ZLIP同時處理4個TCP連接（2個作為客戶端、2個作為服務器端）、兩個UDP連接和PING功能的能力。
以(yi)上例子的(de)代碼如下（該代碼讀者可稍作了解，詳細(xi)的(de)分析需參(can)考Socket API）：
