Ubuntu 下使用BeagleBone Black(一)

Ubuntu 下使用BeagleBone Black(一)

      很奇葩地发现不能插入word文档，另外图片也没办法插入，所以只能剩下这光溜溜的文字了！

      现在花点时间把最近这几天学习过程中的一些经历记录下来，如果需要或者有什么可以交流的请留言……

      原本没有打算使用Ubuntu，但是发现新版本的CentOS7在平时使用确实不好用，至少可以说在应用程序来源和安装上会不方便多了，当然对于CentOS6.5还是不错的，这里并没有说CentOS不好，而只是作为个人桌面系统比较不合适，比如说无限上网卡还要自己安装驱动、NTFS不能自动挂在（需要自己安装相关插件），mp3格式的音频资料不能直接播放……，当然这里面像对于Windows而言，在节能方面linux有待改善~,另外，差点忘记的一点就是对中文输入法的厌恶，只有用了该系统的朋友就能发现其中的奇葩之处！

       为了学习好东西，为了省去比必要的版权问题，为了更好地进入状态毅然面对重重困难选择Linux……

       现在，不说太多的废话，现在开始进入正题：使用Kermit登录BeagleBone Black^

The very long standard initialization file that was distributed
with C-Kermit 6, 7, and 8 is no longer recommended as "standard",
since its features were little used.  It is still available in
the C-Kermit distribution as ockermit.ini.
