Linux+EC20 撥號（）上網或者Gobinet上網方式的實現

1. 撥號（ppp）上網的實現：

1.1插上pcie ec20,保證系統可以識別到：

lsusb -v

Bus 002 Device 002: ID 2c7c:0125
Bus 001 Device 001: ID 1d6b:0002
Bus 002 Device 001: ID 1d6b:0002
 

可見ec20 (2c7c:0125)已經正常認識到；

1.2：

添加usb2serial驅動：

1.3：

ls -la /dev/ttyUSB*

crw-rw----    1 root     dialout   188,   0 Jan 11 06:32 /dev/ttyUSB0
crw-rw----    1 root     dialout   188,   1 Jan 11 06:32 /dev/ttyUSB1
crw-rw----    1 root     dialout   188,   2 Jan 11 06:32 /dev/ttyUSB2
crw-rw----    1 root     dialout   188,   3 Jan 11 06:32 /dev/ttyUSB3

2.Gobinet上網方式的實現：

2.1：

添加驅動：

 

2.2

編譯quectel-CM 工具：

make CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm

2.3

撥號如下：

quectel-CM -s cenet &
