I want to connect one computer to another and basically "chat" with that
computer. I think I would use TCP to do this, but I am not sure how I would
go about doing this. Can someone give me a real bare-bones example of
connecting, sending, and recieving messages? Or at least show me where to
find examples?

if u want use Indy, u can download the indy demo from indy homepage.
i don't sure .. but try to find in www.indyproject.org

there are some sample with indy.

All their examples have to do with using a server and connecting to that. I
just want to connect two PCs, no more. Isn't there an easier way than making
one a server?

Not with TCP.  You can use UDP to send/rx datagrams - this protocol
is message-based rather than streaming & does not have a
client<>server relationship, just a socket at each end.  It's lighter
& quicker than TCP but has no windowed flow-control or error
correction, (rarely a problem on a LAN).

Datagrams as User Datagram Protocol.

From
(http://java.sun.com/docs/books/tutorial/networking/datagrams/definition
.html):
A datagram is an independent, self-contained message sent over the
network whose arrival, arrival time, and content are not guaranteed.

Examples of a datagram client is:

IdTimeUDP.pas

and an example of a server is:

IdTimeUDPServer.pas

Please see the files listed above.  Some things to note about datagrams
are these:

1) There is no such thing as a descret connection with UDP.
2) You have to have a mechanism for ensuring ensuring reliability or you
must be willing to accept some data loss.  Datagrams may not arrive in a
specific order.

and

3) A datagram should probably be no more than 548 bytes unless you know
that all networks and routers the packet will go through can handle much
more.  The 548 value was taken from a FAQ at http://www.manualy.sk/sock-
faq/unix-socket-faq-5.html which is good reading anyway.

HTH.

If its only 2 clients you could use TIdSimpleServer and connect to that but
its just as easy to use a normal server.  Every TCP connection needs a
server (a listening socket) but this does not necessarily mean it serves
many clients.
