Улучшение работы модема IDC 5614BXL/VR+ (24 прошива)

[АБСЕНТ]

Раньше был, модем USR sport 33600 (V.92). Коннектился как минимум на 33600, и работал стабильно (индикатор активности горел постоянно).
Теперь у меня IDC 5614, и работает с включенным V90 крайне не стабильно. Включил V34, но коннект теперь 28800.
Вот статистика, что можно сделать. Никакой строчки инициализации в виндах не прописано

Включил V43 прописав в терминале AT+MS=11
По всей видимости данная комманда была сохранена в эноргонезависимой памяти. Так как в свойствах модема, в виндах строка инициализации была пуста.

Вот сейчас ради экспиремента, вписал такую (увидел на вашем форуме)
S210.7=1 S91=15 S210.4=1 S202.5=1 +MS=,,,,,,14400

Я просто чайник в этом новом для себя модеме, хотелось бы услышать хотя бы примерное место где копать.... модем в приницпе недешевый, а качество не совсем то как ожидалось
