    New features and commands:

            connect message will like "CONNECT  16800/ARQ/V42b/ZyXEL".
            *Note: This feature only available in 1 Mega EPROM.
            *Note: This message will cause problem if your BBs also for
                   automatic fax receiving because the " ZyXEL " message causes
                   the mailer switch to fax receive mode. Please use X6 in this
                   case.
