Well... look at the code!

Socket>>ping: hostName
    "Ping the given host. Useful for checking network connectivity. The 
host must be running a TCP echo server."

In other words, Socket>>ping does not do a "normal" ICMP ping, but 
rather tries to connect to a remote server running an echo service on 
TCP port 7.

Try telnetting to that server on port 7 and see what happens.
