GPRS и Samsung E-900. Непонятные проблемы :-( ( GPRS и Samsung E-900. Непонятные проблемы :-()

[amaliuk]

Есть телефон Samsung E-900 с USB дата-кабелем PCB200BBE. Дистрибутив - Fedora Core 6. Ядро Linux fedora 2.6.20-1.2933.fc6 #1 SMP Sat Mar 10 19:15:16 EST 2007 i686 i686 i386 GNU/Linux. Версия pppd 2.4.4

После подключения телефона в /var/log/messages:
$ tail -f /var/log/messages

Особенно настораживает строка Mar 23 18:18:52 localhost kernel: rndis_host 4-1:1.1: RNDIS init failed, -110.

Телефон на /dev/ttyACM0 нормально опрашивается через minicom. Пробую соединиться с помощью связки pppd + chat script:

В чем тут грабли?

Вообще-то поиск по форуму Вам помог бы..
у меня GPRS+IrDA
Подключаюсь таким скриптом. Спасибо за помощь на форуме.

переделайте под свое устройство (MODEM=xxx) и под своего провайдера (MODEM_INIT=xxx PHONE=xxx), кстати, эксперементировал со значениями mtu, mru - при уменьшении получаю ощутимую прибавку в скорости, начинал с 576 остановился на значении 296. Еще бы операторы компрессию включили!
