#Linux #minicom

本文介绍了一位用户在Arch Linux系统中安装Minicom后遇到的问题，即在调用minicom命令时出现错误提示minicom:cannotopen/dev/modem:Nosuchfileordirectory。通过创建一个软链接将/dev/ttyS0链接到/dev/modem，成功解决了该问题，并最终使Minicom能够正常运行并接收开发板的串口信息。
昨天用pacman -S minicom命令在archlinux上下载并安装了minicom，但是调用minicom命令时出现如下错误：
minicom: cannot open /dev/modem: No such file or directory
今天终于找到解决方案，做一个软链接到/dev/ttyS0就可以解决问题了。命令如下:
ln -s /dev/ttyS0 /dev/modem

minicom命令正常运行后，打开开发板电源，屏幕上出现预期的来自开发板串口的信息。

打开minicom出现以下问题： minicom: can not open /dev/USB0：没有那个文件或目录 因为之前的USB接口是USB0， 重装系统后想也没想就直接将minicom的 Serial Device设置成/dev/USB0 总是启动不了。 事实上，ubuntu识别每个串口设备，其识别的名称可能不一样，需要根据其具体情况进行设置，可以通过以下命令查看具体的信息： ls /de...

由于要修改开发板中的IP地址，于是想到要修改/etc/init.d/rcS，可是由于使用vi rcS后出现乱码，于是想到将rcS复制到主机上修改后在放回到开发板上。于是就悲剧了，修改后放回到init.d目录下，然后重启，就一直不断的出现can't open /dev/tty2: No such file or directorycan't open /dev/tty3: No such file or directory看了它的输出信息，主要是没有访问权限。后来发现其实已经启动了系统，只是没有显示QT界面，
