I did this:
  TComPortReadThread=class(TThread)
  private
    FBuffer: TBytes;
    FReadPacketSize: integer;
    FReadTimeout: integer;
  public
    MustDie: boolean;
    Owner: TFpSerialPort;
    constructor Create; override; //<= THIS ADDED, GIVES ERROR
    property ReadPacketSize: integer read FReadPacketSize write
FReadPacketSize; //How many bytes to read in each operation
    property ReadTimeout: integer read FReadTimeout write
FReadTimeout;    //Max time to wait for data in thread
  protected
    procedure CallEvent;
    procedure Execute; override;
  published
    property Terminated;
  end;


and the code will not compile:

fpserialport.pas(41,17) Error: There is no method in an ancestor class
to be overridden: "constructor Create;"

So, does TThread not have a constructor????
I thought all objects had.
