Serial console
Updated: 12/29/2017 by Computer Hope
The serial console is a connection over the RS-232 or serial port connection that allows a person access to a computer or network device console. Usually, a console is accessed over an SSH (secure shell) connection. However, with software, hardware, or other access problems, it may only be possible to access the machine or device (e.g., router) over a serial connection. Older computers and headless computer (computers or devices without monitors) also use the serial console as the main way to access the console.
