Too bad that most devices/mobiles don't support it correctly. If your device suports MMS MT, and you SMS notifications instead of polling, kannel would gladly accept whatever number of messages per second your device sends. If your mobile supports MMS MO, you can activate an mms option in your smsc group and ask kannel to try to send messages in burst mode. > If I remove the keepalive cmd command at least that will be one less at > command the modem has to handle. + my modem says it supports xon/xoff > software flow control so I might change the com port settings in my > bios. don't use polling. As someone already said, polling is a last resort for very broken devices. You should get notification working (by massaging CNMI) and let polling only for situations like on connect, to grab messages from sim/device memory.
