what component package are TCPClient, TCPserver from?

Indy is blocking, ie. you say
s := IdTCPClient1.IOHandler.ReadString;
showmessage(s);

the showmessage line will not occur until indy has received the string
if, for example you were using a non-blocking componet set such as Fracois Piette's ICS
you would use the OnDataAvailable event, and use a buffer, and showthemessage once you had received an end of string delimiter (e.g. #1 or #13#10)
(you can change it to "linemode" to make this as easy as indy)

The most popular TCP components are (in no particular order)
Indy's TidTCPClient, TidTCPServer
ICS TWSocket, TWSocketServer
Delphi's native TSocket and TServerSocket

oh right, delphi 7. yeah, they're almost the same as the TSocket and TSocketServer from previous versions of delphi.
They can be blocking or non-blocking whereas Indy is blocking
Indy is a 3rd party component set.
Probably more demos for Indy than borland's TTCPClient and TTCPServer, but Indy has some flakey versions.
The Indy9 that ships with delphi is not really supported anymore.
The Indy 10.0.5.2 version had some big changes, and some horrid bugs.
The latest snapshot Indy 10 is reasonably stable for me, but does not have many demos for it.
In saying that, I have made several demos for various versions of Indy, including the latest, and it's pretty easy to learn and work with
