int getEcho (XTC3String *val, char* ErrMsg, unsigned short *len, BOOL TCP);

at most 16 characters and receiving back the same string.
Arguments
XTC3String *val:
Holds the echo string
char* ErrMsg
unsigned short *len
BOOL TCP
Example
#include "XTC3Lib.h"
void main()

if(StartSocket()==0)
printf("Socket could not be initialized.");
if(!ConnectSocket("10.211.70.209"))
printf("Socket could not be connected!");
char ErrStr[256];
memset(ErrStr,0,256);
XTC3String str;
strcpy((char*)str.m_Data,"Are you there?");
unsigned short length = strlen((const char*)(str.m_Data))+1;
BOOL TCP = TRUE; // TCP/IP comm
getEcho(&str, ErrStr, &length, TCP);
if(*ErrStr == 0)
{
printf("Data Transfer successful\n");
printf("The returned string is %s\n",str.m_Data);
