Here is a short list of available packages, their composition and some features. I could not describe all of them in detail within the framework of this book, even if I wanted to. In general, there is no particular need for this: all packages are supplied in source code, many are provided with comments and sometimes good demo applications, so it will not be difficult to figure it out.
I.KOLSocket: This package contains a socket object, along with a visual mirror. As a demo application, an example of working with Telnet. Author Alexander Shakhaylo (Ukraine).
II.TCPSocket: The author of this package is Roman Vorobets. The package contains definitions of TCPServer and TCPClient objects, there are MCK mirrors for both objects.
III.TKOLServerSocket & TKOLClientSocket: Adaptation for KOL (with mirrors for MCK) TServerSocket and TClientSocket components from VCL. Author Alexey Sapronov.
IV.XSocket: Packet for connection via TCP / IP sockets, based on Marat Shamshiev's code. There are no visual mirrors. Perhaps the most compact in code size option, albeit somewhat in the Spartan style. The adaptation for KOL was done by Roman Vorobets.
V.ClientServer: Another socket option without visual mirrors. There is a demo client-server. Posted by Mike Sevbo.
VI.KOL IPC Streams: Objects for working with pipes and milslots * via streams based on the PStream object from KOL. Written by Thaddy de Koning (Nid.)
VII.Synapse: Library of network functions. The adaptation for KOL belongs to Bohuslav Brandys (Poland).
VIII.KOL ICS: Library of objects for developing network applications (Http, Smtp, Ping, etc.). Author Dmitry Zharov aka Gandalf.
IX.KOLHttp: An object for downloading the content of WEB pages from the network via the http protocol. Author Alexander Shakhaylo (Ukr.).
X.KOLFTP: Object for uploading files from an FTP server and uploading files to an FTP server. Author Alexander Shakhaylo (Ukr.).
Note: KOLIndy packages I deliberately did not include them in the list, since they are not completed and, most likely, will not be completed.
