How to view serial port devices on Linux?

You can use the dmesg command in Linux to view serial port devices.

1. Open the terminal.
2. Run the command “dmesg | grep tty”. This command will display all serial devices detected during system startup.
3. Find the serial device you wish to view, usually starting with ttyS or ttyUSB, and make a note of the device name.
4. By entering the command ls -l /dev/tty*, you can display all symbol links of serial devices.
5. Search for symbolic links containing the previously remembered device names, which are typically located in /dev/ttyS* or /dev/ttyUSB*.
6. Choose one device to connect based on your needs.
