A person can access a computer console or network device using the serial console, which is a connection through an RS-232 or serial port. A console is usually accessible through an SSH connection. However, it may be feasible to access the computer or device via a serial connection if there are software, hardware, or other access issues. The serial console is also the primary method for accessing the console on older computers and computers without peripherals (computers or gadgets without monitors). We have mentioned below the steps to connect to a serial console in Linux.
