篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Linux系统通过com口配置交换机相关的知识，希望对你有一定的参考价值。
1、Linux服务器配置交换机的环境
a、通过网络远程连接到Linux服务器或在本地使用linux服务器，用linux服务器的com口连接交换机的console口，在linux服务器上面安装minicom 软件配置交换机。
b、如果没有安装minicom , yum安装方式如下:
yum install -y minicom 安装com 串口通信工具，类似windows系统的超级终端。
安装完成，需配置才可使用minicom通过com口配置交换机；
2、配置minicom软件
a、配置前先检查
[[email protected]_server ~]# ll /dev/ttyS* 显示串口完整路径
crw-rw---- 1 root dialout 4, 64 Jul 2717:56 /dev/ttyS0
crw-rw---- 1 root dialout 4, 65 Jul 2701:10 /dev/ttyS1
crw-rw---- 1 root dialout 4, 66 Jul 27 01:10/dev/ttyS2
crw-rw---- 1 root dialout 4, 67 Jul 2701:10 /dev/ttyS3
[[email protected]_server ~]# dmesg | grepttyS* 执行此命令检查
console [tty0] enabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 检查到linux com 0口识别出console线已连接
00:03: ttyS0 at I/O 0x3f8 (irq = 4) is a16550A
b、minicom配置如下
执行命令 ：minicom –s 编辑串口通信工具，使linux 可以通过com口配置交换机

选择Save as df1。
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。
Exit from minicom 。
选择Exit from minicom 选项从配置菜单返回到命令行。
输入 Minicom 就可以配置交换机了
使用minicom 启动minicom在linux下通过串口连接路由器，实现超级终端的功能。
# minicom 则可以进入了
