function Echo(AText: String): String;
Echo monitors the time needed to send the echo request and receive the echo response, and stores the elapsed time in EchoTime. Echo uses GetTickCount, from IdGlobal.pas, to retrieve both the starting and ending milliseconds measurements used to determine EchoTime. Echo can account for TickCount reverting to a 0 (zero) value after starting the Echo transmission.
