  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

  [ 0.497563] usbcore: registered new interface driver usbfs

  [ 0.497574] usbcore: registered new interface driver hub

  [ 64.362942] usb 6-1: pl2303 converter now attached to ttyUSB0

  [ 64.362970] usbcore: registered new interface driver pl2303

  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 http://www.linuxidc.com

  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
