Сомнения ! VR или VR+

[Oleg_Sh]

Приобрёл сегодня IDC-5614BXL/VR по подозрительно низкой цене (1779р), правда в магазине распродажа и ближайших поставок не ожидается. О модеме: Связь, откровенно говоря, намного стабильнее по сравнению с шитым-перешитым acorp emsf-1, СPS поднялся в среднем на 10-15% ! Решил попробовать прошивки 2.25, 2.26., но усомнимнился в версии модема. Вот, что в терминалке:

ATI6
RCV56DPF-PLL L8571A Rev 43.07/43.07

Всё-же думаю, что это версия с плюсом. Но отелось бы не гадать, а получить одназначный точный ответ.

И ещё. Есть ли смысл пробовать прошивки ? Изменены ли в них алгоритмы выбора скоростей и т.д ? Вот статистика с 2.24. Настройки по дефолту.
