Manual:System/Serial Console

Applies to RouterOS: v3, v4, v5+

Overview

Sub-menu: /system console, /system serial-terminal

Standards: RS-232

The Serial Console and Terminal are tools, used to communicate with devices and other systems that are

interconnected via serial port. The serial terminal may be used to monitor and configure many devices - including

modems, network devices (including MikroTik routers), and any device that can be connected to a serial

(asynchronous) port.

The Serial Console feature is for configuring direct-access configuration facilities (monitor/keyboard and serial port)

that are mostly used for initial or recovery configuration.

If you do not plan to use a serial port for accessing another device or for data connection through a modem, you can

configure it as a serial console. The first serial port is configured as a serial console, but you can choose to

unconfigure it to free it for other applications. A free serial port can also be used to access other routers' (or other

equipment, like switches) serial consoles from a MikroTik RouterOS router. A special null-modem cable is needed

to connect two hosts (like, two PCs, or two routers; not modems). Note that a terminal emulation program (e.g.,

HyperTerminal on Windows or minicom on linux) is required to access the serial console from another computer.

Several customers have described situations where the Serial Terminal (managing side) feature would be useful:

•• on a mountaintop, where a MikroTik wireless installation sits next to equipment (including switches and Cisco

routers) that can not be managed in-band (by telnet through an IP network)

•• monitoring weather-reporting equipment through a serial port

•• connection to a high-speed microwave modem that needed to be monitored and managed by a serial connection
