Answer 1

You should be able to send, but only after the client connects to your server.

When a client connects you should handle OnConnect event of your TIdTCPServer component. AThread parameter represent your client. You can respond to it by, for example:

AThread.Connection.Write ('Hi!');

You can disconnect the client by:

AThread.Connection.Disconnect;

Of course, many clients can be connected at the same time. In this case, you should keep track on all (dis)connected clients.
