This will show the log on the fly of the Linux about what is going on

2) open the another terminal, input command

10.2.4 設定 PPP 裝置

如果您透過 modem 來撥接上網的話，這樣的連線被稱為 Point-to-Point (PPP) 協定。這樣連線作業的網路裝置為 ppp0 , ppp1 等等。

一個 PPP 裝置是由 pppd 這個 PPP 服務所管理，您可以在 ppp 套件中找到該程式。 因此，設定 PPP 裝置也就是設定 pppd 的意思。

 

5) pppd off

6) eject the 3G card
sudo cardctl eject
