After  the BBS  disconnects (hangs up),  you will probably see
        NO CARRIER on  your screen.   Approximately  30  seconds after
        the disconnect,  the BBS will try to call you back.   When you
        see RING on your screen,  or hear the phone ringing,  type ATA
        and press enter.   Wait, without pressing any keys,  until you
        see a CONNECT message.  Shortly after you see CONNECT, the BBS
        will ask for your login password.   After entering the correct
        password, your security status will be upgraded immediately.
