Use equipment: usb-serial adapter

1. Determine the usb device name

Open the terminal and use the dmesg command

You can see that usb is connected to the ttyUSB0

Check to see if the file is available under / dev

You can see that the file exists.

Then using putty / dev/ttyUSB0 should be fine. But it backfired.

2. Putty failed to open the serial connection normally.

$sudo putty

You can open the connection in surprise.
