Linux serial port description-general Linux technology-Linux technology and application information. For details, refer to the following section. I am a system integration engineer, so I often use notebook to debug the ROUTER or SWITCH in my daily work. However, when the operating system is changed to linux, I am dumb, I have also referenced some materials on the Internet. Based on my actual situation, the content is as follows:
1. Check the port number of the USB to comport: demesg | grep usb
For example
"USB Serial: USB Serial Driver core
USB Serial: USB Serial support registered for ftdi usb Serial Device
Usb 4-1: ftdi usb Serial Device converter now attached to ttyUSB0"
Because the serial port driver is FTDI, it corresponds to ttyUSB0.
2. Input in Terminal Mode
Minicom-s (under sudo)
+ ----- [Configuration] ------ +
| Filenames and paths |
| File transfer protocols |
| Serial port setup |
| Modem and dialing |
| Screen and keyboard |
| Save setup as dfl |
| Save setup as... |
| Exit |
| Exit from Minicom |
+ -------------------------- +
3. Go to "Serial transfer protocols"
4. Select A-Serial Device:/dev/ttyUSBX (X is the value found by dmesg)
5. Select E and then select E.
Note: 1. After each item is configured, press enter to save it;
6. Change F-Hardware Flow Control: value to NO
7. Select Exit from Minicom.
