I was trying out the demo. Could open port, but the memo only displayed whatever i sent. For example, if I send AT, it displays AT. The original synaser demo worked fine. I tried adding sleep(3000) as follows, but it doesn't help. What have i done wrongly?
procedure TFMain.SerialRxData(Sender: TObject);
begin
sleep(3000);
Memo.Lines.Add(Serial.ReadData);
end;
