Configuration and use of minicom

安装配置minicom
--------------------------------------------------
# lsmod | grep usbserial (如果直接使用串口线，而没有用到USB转串口设备，此步可以跳过)。如果有usbserial，说明系统支持USB转串口。
或者输入命令： dmesg| grep usb 查看usb串口，注意倒数第三行写着：usb2-10: ch341-uart converter now attached to ttyUSB0。现在你可以用ttyUSB0当串口了。

安装minicom
apt-get install minicom
apt-get install lrzsz

配置minicom
# minicom -s
Serial port setup [Enter]
    +-------------------------------------------------------------+

    PC机向开发板发送文件，需要发送的文件在/tmp目录下(PC机上的目录)。做了此项配置后，每次向开发板发送文件时，只需输入文件名即可，无需输入文件所在目录的绝对路径

开发板 ---> PC
--------------------------------------------------
    开发板上的(操作)命令
    # sz filename
    开发板上的文件filename将被传输到PC机上~目录下
