Serial Console Configuration; Configuring Console - MikroTik RouterOS v2.9 Reference Manual

Description
The Serial Console (managed side) feature allows configuring one serial port of the MikroTik
router for access to the router's Terminal Console over the serial port. A special null-modem cable
is required to connect the router's serial port with the workstation's or laptop's serial (COM) port. A
terminal emulation program, e.g., HyperTerminal, should be run on the workstation. You can also
use MikroTik RouterOS to connect to an another Serial Console (for example, on a Cisco router).
Several customers have described situations where the Serial Terminal (managing side) feature
would be useful:
• in 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-console
• connection to a high-speed microwave modem that needed to be monitored and managed by a
serial-console connection
With the serial-terminal feature of the MikroTik, up to 132 (and, maybe, even more) devices can be
monitored and controlled
