Using Serial Terminal

Command: /system serial-terminal

The command is used to communicate with devices and other systems that are connected to the router via serial port.

All keyboard input is forwarded to the serial port and all data from the port is output to the connected device. Ctrl-A

is the prefix key, which means that you will enter a small "menu" by pressing this combination of keys. The Ctrl-A

character will not be sent to your device! If you need to send Ctrl-A character to remote device, press Ctrl-A twice.

After exiting with Ctrl-A and then Q, the control signals of the port are lowered. The speed and other parameters of

serial port may be configured in the /port directory of router console. No terminal translation on printed data is

performed. It is possible to get the terminal in an unusable state by outputting sequences of inappropriate control

characters or random data. Do not connect to devices at an incorrect speed and avoid dumping binary data.

Property Description

port (string; Default: ) Port name to use

The serial port to be used as a serial terminal needs to be free (e.g., there should not be any serial consoles, LCD or

other configuration). Chack the previous chapter to see how to disable serial console on a particular port. Use /port

print command to see if some other application is still using the port.

Ctrl-A have special meaning and is used to provide a possibility of exiting from nested serial-terminal sessions:

To send Ctrl-A to to serial port, press Ctrl-A Ctrl-A

Note: When rebooting a RouterBoard the bootloader (RouterBOOT) will always use the serial console

(serial0 on RouterBoards) to send out some startup messages and offer access to the RouterBOOT menu.

Having text coming out of the serial port to the connected device might confuse your attached device and get

stuck on boot loader. To avoid this you can reconfigure RouterBOOT to enter the RouterBOOT menu only

when a DEL character is received.

Example

To connect to a device connected to the serial1 port:

[admin@dzeltenais_burkaans] > /system serial-terminal serial0

[Ctrl-A is the prefix key]

[admin@R2] /ip address>
