Модемы U.S.Robotics » Как поднять скорость, посоветуйте plz
Student from Vladivostok All Вторник, Декабрь 11, 2001 - 17:11:

Посоветуйте, пожалуйста, что подкрутить чтобы поднять скорость. АТСка новая, цифровая, но макс. коннект 44000, потом скорость падает. Конденсатор из розетки выдрал, скруток нет. Вот статистика, буду очень благодарен за помощь.

Попробуй регистр S39=12~13, и выложи статистику.
У тебя выходной сигнал глушит все.

Поставил S39=12 (при 13 плохо коннектится), вот статистика
