Hello i how can get only the ports enabled i got big list but i get connect to any support on lsubs show port usb002 is my modem but on synapse don't show up like that how get only the port used or enables

procedure TmainFrm.FormCreate(Sender: TObject);
var
 sr: TSearchRec;
 r: integer;
begin
 ComboBox1.Items.Clear;
 r:= FindFirst('/sys/class/tty/*', faDirectory, sr);
 while r = 0 do begin
  if (sr.Name[1] <> '.') and DirectoryExists('/sys/class/tty/' + sr.Name + '/device/driver')
  then ComboBox1.Items.Add('/dev/' + sr.Name);
  r:= FindNext(sr);
    end;
 FindClose(sr);
end;

The presence of the "device/driver" subdirectory distinguishes a real hardware port.
