How to deal with the problem that when the command box pops up and the content cannot be entered when deploying the serial port debugging environment in putty? I believe some friends still don’t know. For this reason, the author here will share with you the solution to the problem of being unable to enter content when the command box pops up when puttingty deploys the serial port debugging environment.

The port (Serial Line) needs to be set. By default in Linux, after the serial port is connected, the port is dutyS0, or ttyUSB0 (corresponding to USB to serial port). If one more is connected, ttyS1 or ttyUSB1 will be displayed;

In Windows, ordinary serial ports correspond to COM1 and COM2, and USB corresponds to COM3 (you need to install the driver, check the specific COM number in the device manager). Then just set the baud rate.

After clicking the open button, you can enter the linux command in the command interrupt without any intermediate steps (after connecting the Window ordinary USB, you have to use adb shell to enter the android system). At the same time, you can also view the debug information, and the system will automatically print it out.

The above explains how to deal with the inability to input content when the command box pops up when deploying the serial port debugging environment with putty. I hope friends in need can learn from it.
