ββGood day, please check out a new Delphi example that starts listening to an incoming connection, accepts the connection, receives all data over the established connection, and sends no data back to the client. This functionality might be useful when you debug a Network app and want to analyze the produced TCP traffic, e.g. using Wireshark.
The program uses the TcpServerConnection socket class from the Clever Internet Suite library to start listening on the specified local port and receive TCP packets over the Network.
