Ping Component [IP*Works! V8]
Properties

Configuration Settings
The Ping component encapsulates ICMP ECHO functionality, used
to check whether there is a communications link between two
computers.
NOTE: What follows is a very short description of the component interfaces.
For more information, please consult the help files that come with the respective package.
Remarks
When the PingHost method is called with the Host parameter, or
RemoteHost is assigned an IP address or domain name, the
component sends an ICMP ECHO packet to the remote host.
The ResponseTime and ResponseSource properties
are updated with the time of the roundtrip to the remote host, and
the address of the host actually sending the response.
The component operates synchronously by default (waits for a response before
returning control to the caller), however, the component may also operate
asynchronously (return control immediately), by setting Timeout to 0.
Please refer to the Timeout property for more information.
