It is very difficult, for those just starting out, find a good tutorial. On most sites, including the officers, the available information is poor and the reference dates are too old. Gives the impression that the project was abandoned. Well, the fact is I'm looking for a tutorial on idTCPServer and IdTCPClient. Who can help, thank you. Take this opportunity to ask if anyone knows the book Indy in Depth, if it's worth buying it.

Search for Remy Lebeau's posts on StackOverFlow.com or in this forum. Plenty of material.
