the return value does NOT determine if the remote host is alive or
not since the full TCP three-way handshake may not have completed
yet. The remote host is only considered reachable if it receives
-a TCP ACK within the timeout specifed. To begin waiting for the
+a TCP ACK within the timeout specified. To begin waiting for the
ACK packets, use the ack() method as explained below. Use the
"syn" protocol instead the "tcp" protocol to determine reachability
of multiple destinations simultaneously by sending parallel TCP

Create a new ping object. All of the parameters are optional. $proto
specifies the protocol to use when doing a ping. The current choices
1024.
If $device is given, this device is used to bind the source endpoint
-before sending the ping packet. I beleive this only works with
+before sending the ping packet. I believe this only works with
superuser privileges and with udp and icmp protocols at this time.
+If $tos is given, this ToS is configured into the socket.

Ping the remote host and wait for a response. $host can be either the

undef. In list context, the host, the ack time, and the
dotted ip string will be returned instead of just the host.
If the optional $host argument is specified, the return
-value will be partaining to that host only.
+value will be pertaining to that host only.
This call simply does nothing if you are using any protocol
other than syn.
