[root@1jjk liuqi]# minicom -s
时会出现配置界面：
┌─────[configuration]──────┐
│ Filenames and paths │
│ File transfer protocols │
│ Serial port setup │
│ Modem and dialing │
│ Screen and keyboard │
│ Save setup as dfl │
│ Save setup as.. │

└──────────────────────────┘
我的配置是这样的：
[root@1jjk liuqi]# cat /etc/minirc.dfl
# Machine-generated file - use "minicom -s" to change parameters.
pr port /dev/ttyUSB0
pu baudrate 115200
pu bits 8
pu stopbits 1
pu rtscts No
pu xonxoff No
pu askdndir No
[root@bogon liuqi]#
接着可以试一试：
[root@1jjk liuqi]# minicom
