3G 华为ET128在TQ2440上的移植和使用（二）
开启开发板（内核就是TQ的基础上+上前面的配置，文件系统直接用TQ的） 进入文件系统：
(1) /etc/init.d/rcS
mount -a
mkdir -p /dev/pts
mkdir /var/run
mount -t devpts devpts /dev/pts
mount -t usbfs usbfs /proc/bus/usb
(2)
[root@EmbedSky /]# mount -t nfs 192.168.1.28:/nfs /mnt -o nolock
[root@EmbedSky /]# cd /mnt/
[root@EmbedSky /mnt]# ls

执行 pppd call gprs即可拨号
[root@EmbedSky /]# pppd call gprs
（如果出现报错couldn't open ppp database /var/run/pppd2.tdb这一个错误
解决办法
mkdir /var/run
解释:pppd2.tdb这个文件是pppd程序生成的如果没有run这个目录的话只要建一个目录就可以了）
