TIdIOHandler.WriteLn Method

Writes a string value to IOHandler.

procedure WriteLn(
    const AOut: string = ''
); virtual;
Value to send to the IOHandler connection. Default value is ''. 

WriteLn is a virtual procedure used to send the string value specified in AOut to the IOHandler. 

WriteLn appends the EOL character to the valuein AOut, and calls Write to concatenated value to the write buffering mechanism for the IOHandler. 

Use Write to send other data types on the IOHandler.
