minicom的配置

minicom的使用：  
需要先对minicom进行配置，不能直接输入minicom，因为minicom运行时默认在/dev下有modem这个目录，而实际并没有，因此要修改默认的配置。一般第一次启动，需要使用命令minicom –s 对minicom进行配置，配置完成后，选择Save setup as df1，以后就可以直接使用minicom了。
（0）安装minicom，未配置前在终端中输入命令minicom，提示如：
#minicom
minicom: there is no global configuration file /etc/minirc.dfl
Ask your sysadmin to create one (with minicom -s).
（1）在root下，输入命令minicom –s，屏幕出现如下的界面：
# minicom -s
minicom: WARNING: configuration file not found, using defaults
             +-----[configuration]------+
             | Filenames and paths       |
             | File transfer protocols     |
             | Serial port setup              |
             | Modem and dialing          |
             | Screen and keyboard      |
             | Save setup as dfl            |
             | Save setup as..              |
             | Exit                                 |
             | Exit from Minicom           |
            +------------------------------+
（2）设置serial port setup
　　使用down箭头选择serial port setup,出现具体各选项的配置：
     +-----------------------------------------------------------------------+
    | A -     Serial Device       : /dev/modem                                     |
    | B - Lockfile Location      : /var/lock                                          |        
    | C -    Callin Program       :                                                     |
    | D -  Callout Program       :                                                    |
    | E -     Bps/Par/Bits        : 115200 8N1                                  |
    | F - Hardware Flow Control : Yes                                          |
    | G - Software Flow Control : No                                           |
     |                                                                                              |
    |     Change which setting?                                                      |
     +-----------------------------------------------------------------------+
说明：
将选项A的值设置为/dev/ttyS0表示是串口1，如用串口2，设置为/dev/ttyS1，依次类推；
将选项E的值（波特率）设置为115200；
将选项F的值（硬件流）改成No；
设置过程中命令的使用，例如需要修改选项A的值，在Change with setting？选项后输入
A则光标转移到A选项后，可以对A选项的值进行修改。
修改完后的界面如下:
      +---------------------------------------------------------------------+
     | A -     Serial Device       : /dev/ttyS0                                       |
     | B - Lockfile Location      : /var/lock                                      |
     | C -    Callin Program       :                                                    |
     | D -  Callout Program       :                                                   |
     | E -     Bps/Par/Bits        : 115200 8N1                                  |
     | F - Hardware Flow Control : No                                         |
     | G - Software Flow Control : No                                          |

     |     Change which setting?                                                   | 
      +----------------------------------------------------------------------+
按回车退回[configuration]界面。
（3）在[configuration]界面中，选择Save setup as dfl。

退出 Serial port setup 后，进入Modem and dialing，设置内容如下 ：

  具体就是去掉A — initing string ……：，B — Reset string ……： K — Hang-up string ……三个配置项，至于为啥要这样子设置，嘿嘿，不清楚了。回头再看，工程呐，有时候必须抱有“不求甚解”的态度，刨根问底的想法我还放其他地方。

 └────────────────────────────────────────────────────────────────────────────┘

而后，退出选择Save as df1选项将修改后的配置信息进行保存为默认的配置选项，再来个Exit from minicom，搞定。。。。

　　选择Save setup as dfl选项将修改后的配置信息进行保存为默认的配置选项。
（4）选择Exit from minicom 。
　　选择Exit from minicom 选项从配置菜单返回到命令行。
（5）重新启动minicom，则可以使用。出现的界面如下：
#minicom

                Press CTRL-A Z for help on special keys
附加说明：
    minicom 启动后,先按 Ctrl+A 键,再按 Z 键(注意不是连续按,Ctrl+A松开后才按 Z) ,进入主配置界面。如按q可退回终端。
