Description: This unit encapsulate the ICMP.DLL into a VCL of type TPing.
Using this object, you can easily ping any host on your network.
Works only in 32 bits mode (no Delphi 1) under NT or 95.
If you wants to build a console mode program, use the TICMP
object. You'll have a much smaller program.
