安装配置minicom并实现通过minicom传输文件
参考文献：嵌入式linux系统与主机通过串口传输文件ubuntu 下minicom的安装及使用操作系统：ubuntu10.04交叉编译器：arm-linux-gcc-4.1.1一、安装配置minicom1、安装minicomlingd@ubuntu:~$ sudo apt－get install minicom2、配置minicomlingd@ubuntu:~$ sudo minicom -s 出现这样的配置界面： +-----[configuration]------+ | Filenames and paths | | File transfer protocols | | Serial port setup | | Modem and dialing | | Screen and keyboard | | Save setup as dfl | | Save setup as.. | | Exit | | Exit from Minicom | +--------------------------+ 选择Serial port setup, 会看到这样的选项： +-----------------------------------------------------------------------+ | A - Serial Device : /dev/ttyS0 | | 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? | +-----------------------------------------------------------------------+输入前面对应的字母即可进入相应的选项。将选项A的值设置为/dev/ttyS0 表示是串口1,将选项E的值设置为115200,将选项F设置为NO（请根据实际情况配置）. 设置默认上传/下载的目录，选择Filenames and paths , 会看到这样的选项： +-----------------------------------------------------------------------+ | A - Download directory : /home/lingd/arm/download | | B - Upload directory : /home/lingd/arm/upload | | C - Script directory : | | D - Script program : runscript | | E - Kermit program : | | F - Logging options | | | | Change which setting? | +-----------------------------------------------------------------------+注意：开发板发送给pc的文件将保存在Download directory所设定的目录中，而pc要下载到开发板的文件保存在Upload directory所设定的目录中 设置完成后，选择”Save setup as dfl”,保存为默认设置.然后选择“Exit”,即可进入Minicom的主界面:Welcome to minicom 2.4OPTIONS: I18n Compiled on Jan 25 2010, 06:49:09.Port /dev/ttyS0
