Try TTCPBlockSocket instead of TBlockSocket.

Help required please.
Something seems broken with Synapse with FPC 3.0.4 on Debian Linux 64 bit.
Using package downloaded from here:
https://sourceforge.net/code-snapshots/svn/s/sy/synalist/code/synalist-code-207-trunk.zip
Here is a very simple test program:
program socksend;
{$IFDEF FPC}{$MODE DELPHI}{$ENDIF}
uses
? BlckSock,sysutils;
var
? Sock:TBlockSocket;
begin
? Sock := TBlockSocket.Create;
? try
??? Writeln('create: ' + Sock.GetErrorDescEx);
??? sleep(500);
//??? Sock.Bind('192.168.254.254','23');
??? Sock.Connect('192.168.254.254','23');
??? Writeln('connect: ' + Sock.GetErrorDescEx);
??? sleep(500);
??? Sock.SendString('{1@1}'+CRLF);
??? Writeln('send: ' + Sock.GetErrorDescEx);
??? sleep(500);
? finally
??? Writeln('finally: ' + Sock.GetErrorDescEx);
??? Sock.Free;
? end;
end.
Running and compiling from terminal:

The equivalent in java works correctly:
import java.io.*;
import java.net.*;
public class TCPClient {
?public static void main(String argv[]) throws Exception {
? Socket clientSocket = new Socket("192.168.254.254", 23);
? clientSocket.setSoTimeout(2000);
? DataOutputStream outToServer = new
DataOutputStream(clientSocket.getOutputStream());
? outToServer.writeBytes("{1@1}" + "\n");
? int c;
? InputStream in = clientSocket.getInputStream();
? while ((c = in.read()) != -1) {
??? System.out.print((char) c);
? }
? clientSocket.close();
?}
}
I am able to connect to device and get response:
$ java TCPClient
(O01 I01)
Even basic telnet works fine:
$ telnet 192.168.254.254 23
Trying 192.168.254.254...
Connected to 192.168.254.254.
Escape character is '^]'.
{1@1}
(O01 I01)
^]
telnet> quit
Connection closed.
$
Any suggestions on what could be wrong?
