在串口输入input keyevent发送按键值给机器

1.adb shell进入android设备或者DEBUG串口中，执行命令input keyevent keycode即可。
例如：input keyevent 66为KEYCODE_ENTER
keycode对应的键值在frameworks/base/core/java/android/view/KeyEvent.java文件中。
KEYCODE和对应的数值在android源码中定义如下：

举例说明：
例如你的板子没有休眠唤醒的按键，而且也没有遥控，此时你就可以使用这种方式操作机器的休眠唤醒了：
rk3288:/ $
rk3288:/ $ input keyevent 223 //机器进入休眠状态
rk3288:/ $ input keyevent 224 //机器进入唤醒状态
rk3288:/ $
输入abc字符到机器的输入框：
//输入字符abc
rk3288:/ # input text abc
