ARM9+linux上使用efax成功实现modem发送传真

之前认真学习过三类传真机收发传真过程，也分析了mgetty-1.1.36（主要在PC上用的）与远端传真机建立连接的部分源码.最后也写了个发送传真的程序。可是到phaseC,modem给远端传真机发送TCF帧后，总不能接受到信号。后来找到了efax这个开源传真软件，efax比mgetty更小巧，使用起来也比较灵活，下面是在ARM9+linux2.6.12上使用modem来发送传真的过程。

1， 交叉编译efax，这个过程非常简单：
                       源代码下载地址：
这里有他的pdf使用说明文档： http://www.cce.com/efax/documentation/


      解压缩下载源代码包：  #tar -xzf efax-0.9.tar.gz  -C /usr/local/src
     
      修改Makefile:     
     CC=arm-linux-uclibc-gcc
     STRIP=arm-linux-uclibc-strip
     并将strip efax  改为 $(STRIP) efax

     #make  

make之后会生成两个文件，efax和efix.  其中efax是用来收发传真的代码，而efix是将我们的普通文件转换成相应的传真文件。源码包里的fax文件是一个shell脚本，主要在这个shell脚本里完成一些传真配置。

2，修改fax这个shell脚本：
< FAX=/tmp/fax        //这里指定fax, efax, efix的path，注意该目录需可写，因为他要写log.当然可以修改源码
< EFAX=/tmp/efax
< EFIX=/tmp/efix
---
> FAX=fax
> EFAX=efax
> EFIX=efix
31c31
< DEV=ttyS4    //这里指定我的modem所在的设备名，我的modem比较多，用的是ttyS4
---
> DEV=cua1

3， 发传真，其中test是我要发的文件，628是传真号码。（我们内部电话只需要拨分机号就OK了）
