Definition

property LineMode: boolean;

Description

If set to true, LineMode enables automatic splitting of received data into packets based on a user definable char sequence.

Example

If the client always sends data lines which end on CR/LF and the server shall display the lines individually in a memo, the server would set LineMode to true so that he always receives whole lines without needing to look for the end of a line himself.

  Socket.LineLimit:=100;             // prevent denial of service or buffer 
                                     // overflows
  Socket.LineEnd  :=chr(10)+chr(13); // the sender has to terminate all 
                                     // messages sent with this character 
                                     // combination
  Socket.LineMode:=true;

In OnDataAvailable ReceiveStr is used to fetch the available data packet by packet.

Best practices

Always set LineLimit to prevent buffer overflows.
