Помогите разобраться

[Dim6I4]

Вот собрал статистику соединения. Слишком много ретрейнов , причем не автоматическиха вынужденых. Подскажите пожалуйста что можно сделать ?

Начните с установки микропрограммы версии 2.26. Затем пересоберите статистику.

Огромное спасибо.
На первый взгляд вроде бы всё хорошо стало после установки микропрограммы. Но зацените с точки зрения специалиста

Ну что же, неплохо!

Попробуйте прописать в строке инициализации в свойствах модема такие команды:

S91=18 S210.7=1 S55.4=1 S202.3=1 S17=64

По всей видимости стало ещё лучше Больше ничего не нужно подправить ? Спасибо !

Пожалуй, на этом и остановимся. Ничего менять не нужно.
