Hi,
I'm using synapse to communicate with a cash drawer on my serial port,
using Lazarus and fpc.
I'm using the following code (lifted directly from the example)
procedure TForm1.ButtonTenderedClick(Sender: TObject);
var ser:TBlockSerial;
begin
showInput;
Panel3.Visible:=false;
LogicPath:=4;
ser:=TBlockserial.Create;
try
ser.RaiseExcept:=True;
ser.Connect('COM1');
ser.Config(9600,8,'N',0,false,false);
writeln (ser.ATCommand(#7));
finally
ser.Free;
end;
end;
Does anyone know if I can interrogate the serial port to find out if
the cash drawer is still open?
