Hi E.DR_91,
The possible causes of the console port login failure are as follows:
Parameters of the serial port are incorrectly configured.
The connection port is incorrectly configured.
Physical attributes of the serial port on the PC are different from the attributes of the console port on the device.
Cables are not firmly connected to the serial interface.

Hi friend!

1. Check whether the communication parameters are correctly configured.

Check whether a correct serial port is connected. Some PCs provide multiple serial ports with corresponding numbers. When connecting a serial port, ensure that the correct serial port number is selected.

Check that the serial port settings on the PC are the same as the console port settings on the device. The default console port settings are as follows:

Baud rate: 9600
Data bits: 8
Stop bits: 1
Parity: None
Flow control: None

Hope to help you!
