Ещё вопросик: А можно посмотреть параметры текущего соединения? С тем чтобы, если соединение плохое, то перезвонить?

[Technical Support]

[sellin]

под "не хочет работать" имею ввиду безпричинный LINK DISCONNECT . Щас попробую со сжатием и коррекцией.

[Technical Support]

LINK DISCONNECT - нормальный разрыв связи по инициативе удалённого модема. При правильной работе модема и софта этот код означает, что софт (в данном случае - маршрутизатор) дал команду на разрыв связи, а модем её выполнил.

Учитывая особенности продукта, причиной выдачи команды на отключение вполне могут быть проблемы с протоколами коррекции.

Спасибо за помощь, связь наладилась, но среднее
cps очень низкое, при закачке около 1000 cps.
Прием данных идет прерывисто. На 4800 v.32 такого
не наблюдается, и в результате в среднем получается
800 cps. Подозрительно маленькая разница...

Вот статистика со строкой
\N5 M4 S202.7=1 S91=11 +MS=11,,,21600,,,14400

Прежде всего, подозрителен сам результат. При скорости в 4800 бит/с теоретическая производительность канала равна 577 байт/с. Реальная производительность даже при идеальных условиях ещё ниже, из-за потерь на накладные расходы протоколов верхнего уровня.

Поэтому единственный способ достичь 800 байт/с при 4800 бит/с - сжатие данных. Это значит, что Вы принимали несжатые данные и следовательно, сравнение заведомо некорректно (степень сжатия зависит от структуры данных).

Вам нужно, во-первых, отключить протокол сжатия MNP-5 (поскольку он не умеет отключаться сам при приёме "несжимаемых" данных, и может снижать производительность). Это делается командой %C0. Во-вторых, нужно провести сравнение ещё раз. При отключённом сжатии можно скачивать любые данные, а не только архивы.

Что касается скорости, то причина проблем может быть в большом количестве перепосылок кадров данных. В какую сторону (т.е. кто ошибался) - выясните экспериментальным путём, "закручивая гайки" на приём и на передачу. Т.е. пробуете +MS=11,,,21600,,,4800. Если результат мало отличается от предыдущего, зажимаете скорость приёма (+MS=11,,,19200,,,4800. Если и тут плохо, то меняете 19200 на 16800 и т.д., пока не получите приемлимый результат. Дальше пробуете убрать ограничение скорости передачи вообще, например:

+MS=11,,,14400

Если ситуация не ухудшилась, так и оставьте. В противном случае снижаете скорость передачи, пока не повторите результат.

Начинаю уменьшать скорость, начинаются ретрейны...ничего не понимаю.
