В чём проблема?

[Nickolay]

Я так понял, что причина моей постоянной скорости 33600 - модуляция V. 34

Почему модем не хочет работать на V.90?

Что значит Reason for V.34 Fallback..... Data Pump decision to Fallback in Phase 2?

ну и если не трудно подскажите, что можно ещё улучшить.

Заранее благодарен.

Перепрошил, прописал строку и что-то стало хуже ;-(((
Модем стал соединяться на 30600 и постоянно "залипать", что приходится пересоединяться.
