Hello!

I switched my net package to Synapse, but I used the Lnet before. So I
need the the most simple tutorial to set Synapse TCP connection. (I'm
not a master of programming, mainly of net-programming).

Others:
-A too long time ago I tried it but it was hard and I left it for Lnet
but Lnet now seems bad.
-What is the bind command?
-Can I set more connection between two device/program than 1?
and I want to use them to categorize the data easyer. For example 5
connection:
1-string messages between users
2-files
3-system messages
....

Please take a look at the following example:

Basically all your requirement is implemented(send/receive message,
streams, files, etc..). After you download the zip, look in the
"Common", search for utcpsockets.pas.

There are more examples, etc. in the Synapse/Synaser website. Though a
little old they are still mostly valid.

AFAIK there is no TCP/IP Client/Server example on Synapse/Synaser
website(I might be wrong though).

There is. If you download version 40 zip (not trunk/svn but the .zip)
you get a demo directory in source-folder. The TCPclient/server is
there.

There is also the wiki page there with some examples (but the tcp
examples are in the zip).

@rvk
Thanks. I didn't know about the demo folder. I guess the EchoSrv(Echo
folder) is the closest to what OP is trying to achieve.
