Francois, I do appreciate your response as I am over my head here.
If server socket is connected to a client socket is there any communication that we can send from the server socket to the client socket that will prevent intermediate firewalls and routers from timing out. If you can recommend some of your examples I will look at them. It has been 4 years but I have reinstalled. As an aside it is a pleasure to get back to Delphi. Thanks for reply. grs > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of Francois Piette > Sent: Friday, March 24, 2006 3:10 AM > To: Borland's Delphi Discussion List > Subject: Re: ping to specific socket port > > > Is there a way to programmatically send a ping to a specific port. > > Port is related to UDP and TCP protocols.
