    Hello, onassis.

    Try to use AT+CFUN command (Set phone functionality):
    This command executes an IMSI DETACH and makes a backup copy of some internal parameters in SIM and in EEPROM. The SIM card cannot then be accessed.
    The AT+CFUN=1 command restarts the entire GSM stack and GSM functionality: a complete software reset is performed. All parameters are reset to their previous values if AT&W was not used.

    If it is not what you want, could you show AT command, you send to modem to turn it off?

    Unfortunatly, I can't show you snippet for Delphi, but here snippet for working with COM-port from VB.
    It works with COM object, so from Delphi it should be nearly the same.

    One more thing I could suggest - is to look in the sources of boomerang library.
    If it is closed sources, then search the gsm.pas file for AT command: AT+CFUN. Which methods call it, if any.
