I need a bit of help with app. I am using lnet and synaser and trying to open multiple sockets. While I can create the sockets, I can only open the first one called. Any Ideas?
//UNIT1
      begin
           server1 := TTCPEchoDaemon1.Create;
           ServerSer := TServerSerial.Create;
           ServerSer.Execute;
           server1.Run;
      end; 
//EO UNIT1
 
 
//UNIT2
constructor TTCPEchoDaemon2.Create;
begin 
  FCon := TLTCP.Create(nil);
  FCon.OnReceive := @OnRe;
  FCon.Timeout := 100; // responsive enough, but won't hog cpu
  FCon.ReuseAddress := True;
end;
 
Constructor TServerSerial.Create;
begin
  Fser:=TBlockserial.create;
//  FreeOnTerminate:=true;
//  inherited create(false);
end; 
 
procedure TTCPEchoDaemon1.OnRe(aSocket: TLSocket);
var
  s: string;
  n: Integer;
begin
  if aSocket.GetMessage(s) > 0 then begin // if we received anything (result is in s)
//   Writeln('Got: "', s, '" with length: ', Length(s)); // write message and it's length
    RecvString(s); //catch full string
    FCon.IterReset; // now it points to server socket
  end;
end;
 
procedure TTCPEchoDaemon1.Run;
var
  Quit: Boolean; // main loop control
  Port: Word;    // the port to connect to
begin
 
    try
      Port := Word(StrToInt(SysPort1)); // try to parse port from argument
    except
      on e: Exception do begin
        Writeln(e.message);
        Halt;
      end;
    end;
    Quit := false;
 
    if FCon.Listen(Port) then begin // if listen went ok
    Writeln('Server running! on '+SysPort1);
       repeat
        FCon.Callaction; // eventize the lNet
      until Quit; // until user quit
    end; // listen
end; 
 
procedure TServerSerial.Execute;
begin
   with Fser do
    begin
    RaiseExcept:=false;
    Connect(PortNo);
     WriteLn('Serial Port Connected');
     Config(Baud,databits,parity,stopbits ,softwarefl,hardwarefl);
      if active = true then begin
         while not (LastError <> 0) do begin
            if lastError<>0 then break;
              if canread(1000) then  begin
              LCMD := Recvstring(1000);
              WriteLn(LCMD);
              myconverterfunc1:=@CallConv1;
              myconverterfunc1(LCMD);
              end;
         end;
      end;
    end;
end; 
 
function TTCPEchoDaemon1.RecvString(S2: String): AnsiString;
var
  n : integer;
  Stringtest : String;
begin
    n := 1;
    while n <= Length(S2) do begin
          if S2[n] = LF then begin
          myconverterfunc1:=@CallConv1;
          myconverterfunc1(Stringtest);
          stringtest := '';
          Delete(S2, n, 1);
          Continue;
          end;
    Stringtest := Stringtest+Copy(S2, n, 1);
    inc(n);
    end;
 
end;
