Linux下如何通过串口连接Cisco交换机

这里推荐用minicom, 通过yum install minicom 或者apt-get install minicom下载并安装minicom

首先执行minicom -s 进入配置页面

            +-----[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        |
            +--------------------------+

首先进入Serial port setup       

把 serial devie 改为 /dev/ttyS0, 把Bps/Par/Bits改为 9600 8N1

----------------------------------------------------------------------+
    | A -    Serial Device      : /dev/ttyS0                                |
    | B - Lockfile Location     : /var/lock                                 |
    | C -   Callin Program      :                                           |
    | D -  Callout Program      :                                           |
    | E -    Bps/Par/Bits       : 9600 8N1                                  |
    | F - Hardware Flow Control : No                                        |
    | G - Software Flow Control : No                                        |
    |                                                                       |
    |    Change which setting?     

回车后退出

再修改Modem and dialing

把Init String和reset string都修改为空白
