首先，安装minicom：sudo apt-get install minicom
在安装好minicom之后对minicom进行配置，在此，需要注意的一点是在Linux环境下不许要装Usb转串口的驱动，在此，使用lsmod命令
z75993971@Ubuntu:~$ lsmod
Module Size Used by
pl2303 13696 0
usbserial 39507 1 pl2303
binfmt_misc 7984 1
可见，linux可以自动识别2303设备
之后在终端中输入dmesg | grep usb命令
z75993971@ubuntu:~$ dmesg | grep usb

注意上面加红的地方，他指明了设备号为：ttyUSB0
之后，就可以进行mimicom的配置了
在终端中输入：minicom -s,选择
+-----[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 |
+--------------------------+
配置成如下方式：
+-----------------------------------------------------------------------+
| A - Serial Device : /dev/ttyUSB0 |
| 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? |
+--------------------------------------------------------------------
完成后退出，退出后进入 Modem and dialing 配置成如下方式：
（原因：我们使用的是串口，而不Modem）
+--------------------[Modem and dialing parameter setup]---------------------+
| |
| A - Init string ......... |
| B - Reset string ........ |
| C - Dialing prefix #1.... ATDT |
| D - Dialing suffix #1.... ^M |
| E - Dialing prefix #2.... ATDP |
| F - Dialing suffix #2.... ^M |
| G - Dialing prefix #3.... ATX1DT |
| H - Dialing suffix #3.... ;X4D^M |
| I - Connect string ...... CONNECT |
| J - No connect strings .. NO CARRIER BUSY |
| NO DIALTONE VOICE |
| K - Hang-up string ...... |
| L - Dial cancel string .. ^M |
| |
| M - Dial time ........... 45 Q - Auto bps detect ..... No |
| N - Delay before redial . 2 R - Modem has DCD line .. Yes |
| O - Number of tries ..... 10 S - Status line shows ... DTE speed |
| P - DTR drop time (0=no). 1 T - Multi-line untag .... No |
| |
| Change which setting? (Return or Esc to exit) |
+----------------------------------------------------------------------------+
配置完成后推出，在退出时一定要选择Save setup as dfl
到此，Minicom的配置完成，连上串口线，打开开发板电源即可看到串口输出的打印信息
===== 三.Minicom的使用 =====
1.minicom的执行
用指令"rpm -qa | grep minicom"来确认是否安装了minicom，回车后会显示minicom 的版本信息．
第一次 启动时：
即输入 minicom提示 错误。则 需： minicom -s
启动
出现配置菜单：选serial port setup
进入串口配置
输入A配置串口驱动为/dev/ttyS0
输入E配置速率为115200 8N1
输入F将 Hardware Flow Control 设 为 NO
回车 退出
由于我们使用minicom作为超级终端控制路由器等设 备, 而不是控制modem, 所以需要修改Modem and dialing, 将Init string, Reset string, Hang-up string设置为空. 设置完成后选择Save setup as dfl将当前设置保存为默认设置.
在配置菜单 选Save setup as df1保存（一定要记得这一步）
选Exit退出
下次在输入minicon 即可直接进入。
命令minicom是进入串口超级终端画面，而minicom -s为配置minicom。
说明/dev/ttyS0 对应为串口0 为你连接开发板的端口。
注意：非正常关闭minicom，会在/var/lock下创建几个文件LCK*，这几个文件阻止了minicom的运行，将它们删除后即可恢复
