gprs module 上网的具体命令有哪些？如何一个顺序？

[hansomenny]

我用的是wavecom q2403 module,带gprs功能。用于smartphone，串口连接于我的硬件。操作系统是winCE 4.2.打电话功能是正常的，gprs上网不行。就是用ATO命令从offline mode 转到online mode返回+CME ERROR: 3错误。我不知道gprs上网的时候用了哪些命令，顺序如何。下面是我gprs上网时用的命令。

1.AT+CGDCONT=1,"IP","cmnet",,0,0<cr>
response: 0<cr>
2.AT+CGQREQ=1<cr>
response: 0<cr>
3.AT+CGQMIN=1<cr>
response: 0<cr>
4.AT+CGACT=1,1<cr>
response: 0<cr>
5.AT+CGDATA=1<cr>
response: 25<cr>+CRING: GPRS
6.AT+CGACT=0,1<cr>
response: 3<cr>
7.AT+CSQ<cr>
response: +CSQ: 24,0<cr><lf>0<cr>
8.ATO<cr>
response: +CME ERROR: 3<cr><lf>
9.AT+CLCC<cr>
response: 0<cr>


下面是我的debug message,请大侠指点
