I am porting an application from Windows Delphi 2007 to FPC on Linux (Raspberry Pi2). In the process I need to switch from using RS232 to TCP/IP to communicate with a data source.

I have found that FPC contains the unit ssockets.pp, which implements a client socket class TInetSocket.

But I need a working example of how this is used so I can start testing if I can use it in my application.

Are there some examples of sending binary data between a TCP/IP server and the TInetSocket socket? If so please post links.

FPC has some TCP/IP (using TInetSocket) demos, and you can see that on its sources, eg:

Client: <FPC folder>\source\packages\fcl-base\examples\dsockcli.pp Server: <FPC folder>\source\packages\fcl-base\examples\dsocksvr.pp

And you can enjoy some third party demos too, take a look at this small project:

Good luck! =)

www.CtrlTerm.com has a simple Synapse example.
