What do You thinking about send At command during invoking stopGateway to
SerialModem.
For example add empty shutdown() method to AtHandler and invoking this
method during stopGateway() like this:

atHandler.shutdown();
super.stopGateway();
driver.disconnect();

I working with your library in company and this is very useful for us. We
need to shutdown modem when our application shutdown. We using in our
Wavecom at handler such method to shutdown our modems (Wavecom M1203A-ON
and Wavecom M1306B):

@Override
public void shutdown() throws TimeoutException, GatewayException,
IOException, InterruptedException {
    modemDriver.write("AT+WATH=31\r"); //Hang up every call
    Thread.sleep(gateway.getService().S.AT_WAIT);
    modemDriver.write("AT+CFUN=0\r"); //Stop GSM stack
    Thread.sleep(gateway.getService().S.AT_WAIT_AFTER_SHUTDOWN);
}

I thing this change is compatibile with previous versions.

Hi,

Yes, such a change would be harmless - I guess this should be placed in the Wavecom
handler.

Out of curiocity, why would you want to shutdown the gsm stack of your modem? Is
there any advantage of doing so?

Yes it can be in wavecom handler. We have three difrent models od wavecom modems and
every model seem to work correctly with these At commands. 

The advantage is that we had problems with our old wavecom modem M1203A that after
reset AT+CFUN=1 modem was still remember the sim pin. We start application and smslib
ask modem about sim status. So modem tell that he require sim pin so we put sim pin
to him. Status now is ready but. When we shutdown application modem is still in
"session" and some other device can sending sms to him and calling. We don't want
such situation. After that we start again aplication and after reset (AT+CFUN=1) we
have still sim pin status = READY. It's not acceptable in our situation so we were
forced to develop shutdown method in atHandler and modify some other controll flow in
disconnect method in ModemDriver as I remember. Similar thing you have after driver
connect() when You invoking atHandler reset() method. This shitdown is invoked at the
beggining of the disconnect() method in modemdriver before disconnect from serial port.
