For protection against unauthorised access, password entry can be
configured. In this case the ZDUE-GPRS-PLUS-VI queries the caller for the
agreed password; the caller must then transmit it during the configured time
period (password timeout). If the password is incorrect or the timeout is
exceeded, the ZDUE-GPRS-PLUS-VI terminates the connection. The
password is parameterisable.
