As its name implies, TWSocketerver is the component you'll use at the server
side (The one waiting for connections from client).
You shall use TWSocket at client side (The one which initiate the connection
to the server).

> 2, need to use linemode? Its lineEnd how to set? Do not set up, wrong, how
to deal with?          

You shall use LineMode if and only if the messages you send are ALL
terminated by the same characters (One of more, default is CR LF pair).
You set LineMode Boolean property to change the behavior.

> 3, need to enable MulitiThreaded?          

You shall probably not use multithread. ICS components multitask without the
need of multithread. You'll only need multithreading if you have lengthy
computation or length database (or similar) access.

> 4,How do WSocketServer receive data ,Is it by ClientDataAvailable?  

TWSocketServer by itself doesn't receive any data, it waits for client
connection. When one client is connecting, TWSocketServer instanciate a
TWSocket to handle that particular client communication.

Have a look at OverbyteIcsSrvTcp.dpr, OverbyteIcsTcpSrv.dpr or
OverbyteIcsTnSrv.dpr projects if you build a GUI server, or
OverbyteIcsSrvTcp.dpr project if you build a service for the server.

Have a look at OverbyteIcsClient7.dpr project to start your client prject.

Objet : [twsocket] I want to receive bin string by wsocketserver

Sir, thank you for your great works.
I want to receive/send binary string by WSocketServer. My client is a GPRS .
1, the send string is binary data , its length maybe 10 byte, 17 byte, 24
byte,  and 40byte   etc.        
2, the send data began as 16 hexadecimal fixed:  FA 21          
3, the end of the data's character is  arbitrary .          
4, after receiving data, do some data analysis, and write some msg to
database.          


There are a few questions to consult ICS Component,          
1, wsocketServer can achieve this function?          
2, need to use linemode? Its lineEnd how to set? Do not set up, wrong, how
to deal with?          
3, need to enable MulitiThreaded?          
4,How do WSocketServer receive data ,Is it by ClientDataAvailable?  


Could you pleased give me some code for this function?
         Thanks


                                               Sun Xiao
