Очень плохая линия

[Eralex]

Ситуация у меня такая - самая отстойная линия в городе,
плюс к этому телефон подключен через АВУ ВЧ.
Вот типична статистика:

Тут что-нибудь можно сделать?

[Technical Support]

15 перетренировок, запрошенных удалённым модемом! И это за меньше, чем 4 минуты... так жить нельзя

Пропишите такую команду в строке инициализации в свойствах модема:

S91=9 S210.7=1 +MS=11,,,,,,7200

и пересоберите статистику.

С той строкой инициализации, что вы посоветовали
я так и не смог вообще до инета достучаться.
После набора номера из модема идут такие долгие
"натужные" звуки (примерно раза 4), а затем
модем бросает трубку. Сейчас пользуюсь такой
строкой: ATM5S210.7=1S55.3=1+MS=10
т.е. соединяюсь на 32 протоколе. Вот статистика:
