visa test panel in NI MAX ver 5.4.0 read timeout

I am using the visa test panel in NI MAX ver 5.4.0 and I connect to a CVI application I currently have a server socket up and running. My server accepts the connection form the visa test panel ok, and when I write from the visa my application sees it immediately. Then I try to read and the visa will timeout, at which point the visa displays what I sent in the 'send' command. I cannot determine why the visa writes to my application ok but the send is not received until the timeout occurs in the visa tool. In my application I am doing a simple 'send' on a valid socket. I am not sure why, but if anyone has any answers I would appreciate it. Here is a snippet of my code in my main:

  char sendbuf[64];
 
  strcpy (sendbuf, "ACK\n");

  /* Initialize WINSOCK before any socket calls are made */
  iResult = WSAStartup(MAKEWORD(2,2), &WSAData);
  if ( iResult != 0 )
   return SOCKET_ERROR;

  if ((ServerSock = SockOpenServer(SERVER_PORT_NUMBER_TCP)) == SOCKET_ERROR)
   return SOCKET_ERROR;
 
  /* By now the socket should be successfully bound.                */
  /* Wait for clients to connect. As each client connects,          */

  AcceptedSock = SockWaitForAccept(ServerSock);

  /* Indicate the socket has been initialized and a client has been accepted */
  if (AcceptedSock > 0)
   isServerInitComplete = TRUE;
  else if (AcceptedSock == SOCKET_ERROR)
   runRDPServer = FALSE;

  while (runRDPServer)
  {

   BytesReceived = recv(AcceptedSock, ptrCh, BytesToRead, 0);

   if (BytesReceived > 0)
   {
    /* for now just send back an ACK to ackknowledge the receipt of data */
    if (strncmp(ptrCh, "*IDN", 4) == 0)
     BytesSent = send(AcceptedSock, sendbuf, (int)strlen(sendbuf), 0 );

    if (strncmp(ptrCh, "*ESE", 4) == 0)
     runRDPServer = FALSE;
   }
  
  }
