Description: 嵌入式Linux下实现GPRS拨号上网 本人使用FriendlyARM开发板（miniARM2440）与GPRS模块（SIM300，用广州动感地带的手机卡，cmnet 连接）实现了基于PPP的拨号上网，方法如下：
1.首先得让内核支持PPP，进入Linux 内核目录（kernel-2.6 或 以上内核版本），执行 #make menuconfig
添加如下内核选项：
Device Drivers ---> Network device support --->
<*> PPP (point-to-point protocol) support
[*] PPP multilink support
<*> PPP support for async serial ports
<*> PPP support for sync tty ports
<*> SLIP (serial line) support
[*] CSLIP compressed headers
