About wattcp, how to set the listening port and receive data?

#include <stdio.h>

#include <tcp.h>



 int main()

 {

  word status;

  word port;

  longword host;

  udp_Socket usock;



  //------//

  sock_init();



  host=resolve("192.168.1.28";

  port=8001;



  //--- OPEN UDP ---//

  udp_open(&usock,0,host,port,NULL);



  //--- SEND DATA ---//

  sock_write(&usock,"发送成功!!",10);



  //--- CLOSE UDP ---//

  sock_close(&usock);



  sock_exit();

 }

The above program can be successfully sent!! The program on the WINDOWS side has already received it!
But I don't know how to write the receiving module on the DOS side!!!!
So annoying~!!!!!!!!!

Everyone, please help me~!!!! Thank you~!

sock_receive()直接收

```c
int revLen;
char revBuff[1024];
udp_open(&udpSock, localPort, 0, 0, NULL);
tcp_tick(NULL); // Give the protocol stack a chance to execute
if ((revLen = sock_dataready(&udpSock)) != 0) // Check if data has arrived
{
sock_fastread(&udpSock, (byte*)revBuff, revLen); // Receive data
}
```

Thanks to the brother above~!

But the packet loss is too serious~!

Gave up~!

Thanks~!
