mc703模块的使用

我是在linux下使用该模块的。内核为2.6.32。

1 在linux中已经有了该模块的驱动，只要照着mc703文档做就行了。

2  像打电话、发短信等功能通发AT命令就可以实现了。

3  关于ppp拨号上网的步骤：

 先在内核中选中支持PPP协议，重新编译内核。

1）  下载 ppp-2.4.4.tar.gz，用交叉编译工具编译

a)       ./configure

b)       make CC=$(CROSS_COMPILE)gcc

c)       把pppd chat拷贝到文件系统的/usr/sbin/下

2）  把下面内容写进evdo中，把evdo拷贝到/etc/ppp/peers/下

debug

nodetach

lock

/dev/ttyUSB0

115200

user "card"

password "card"

crtscts

show-password

usepeerdns

noauth

noipdefault

novj

novjccomp

noccp

defaultroute

ipcp-accept-local

ipcp-accept-remote

connect '/usr/sbin/chat -s -v -f evdo-connect-chat'

disconnect '/usr/sbin/chat -s -v -f evdo-disconnect-chat'

3）把下面内容写进evdo-connect-chat中，

TIMEOUT 5

ABORT 'NO CARRIER'

ABORT 'ERROR'

ABORT 'NO DIALTONE'

ABORT 'BUSY'

ABORT 'NO ANSWER'

'' \rATZ

OK-AT-OK ATD#777

CONNECT \d\c

4） 把下面内容写进evdo-disconnect-chat中

ABORT "BUSY"

ABORT "ERROR"

ABORT "NO DIALTONE"

SAY "\nSending break to the modem\n"

'' "\K"

'' "+++ATH"

SAY "\nGoodbay\n"

5）  执行下面命令

   root@dm365-evm:/etc# pppd call evdo &

   打印出下面信息：

      root@dm365-evm:/etc# timeout set to 5 seconds

abort on (NO CARRIER)

abort on (ERROR)

abort on (NO DIALTONE)

abort on (BUSY)

abort on (NO ANSWER)

send (^MATZ^M)

expect (OK)

ATZ^M^M

OK

 -- got it

send (ATD#777^M)

expect (CONNECT)

^M

ATD#777^M^M

CONNECT

 -- got it

send (\d)

Serial connection established.
