About ping command in NSIS

Now, i need check a host if is connect, i use the ExecWait::cmd.exe ping host, but how i can get the return value from ping, i want to do that:

if connect, show "connect ok"
if can't connect , show "connect time out"

how i can do it , thanks!!

Just because you can ping a host does not mean that other protocols and ports are not blocked. Which service are you trying to use? HTTP?
