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 routersand any device that can be connected to a serial asynchronous port.
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. Several customers have described situations where the Serial Terminal managing side feature would be useful:.
With the serial-terminal feature of the MikroTik, up to and, maybe, even more devices can be monitored and controlled. A special null-modem cable should be used for connecting to the serial console from another computer. The Serial Console cabling diagram for DB9 connectors is as follows:. Note that the above diagram will not work if the software is configured to do hardware flow control, but the hardware does not support it e.
If this is the case, either turn off the hardware flow control or use a null-modem cable with loopback, which will simulate the other device's handshake signals with it's own. The diagram for such a cable is as follows:. Note that although it is recommended to have a 5-wire cable for this connection, in many cases it is enough to have 3 wires for unlooped signals onlyleaving both loops to exist only inside the connectors.
Other connection schemes exist as well. Note: RouterOS 6. To disable all virtual consoles available through the direct connection with keyboard and monitor except for the first one:. 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 Qthe control signals of the port are lowered. 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.
The serial port to be used as a serial terminal needs to be free e. Check the previous chapter to see how to disable serial console on a particular port. Ctrl-A has a special meaning and is used to provide a possibility of exiting from nested serial-terminal sessions:. Having text coming out of the serial port to the connected device might confuse your attached device and get stuck on boot loader. This facility is created to change line number per screen if you have a monitor connected to router.
Jump to: navigationsearch. Categories : Console System Manual. Navigation menu Personal tools Log in.The console is used for accessing the MikroTik Router's configuration and management features using text terminals, either remotely using serial port, telnet, SSH or console screen within Winbox, or directly using monitor and keyboard.
The console is also used for writing scripts. This manual describes the general console operation principles. Please consult the Scripting Manual on some advanced console commands and on how to write scripts. The console allows configuration of the router's settings using text commands.
Since there is a lot of available commands, they are split into groups organized in a way of hierarchical menu levels. The name of a menu level reflects the configuration information accessible in the relevant section, eg. Instead of typing ip route path before each command, the path can be typed only once to move into this particular branch of menu hierarchy.
Thus, the example above could also be executed like this:. Notice that the prompt changes in order to reflect where you are located in the menu hierarchy at the moment. Many of the command levels operate with arrays of items: interfaces, routes, users etc. Such arrays are displayed in similarly looking lists. All items in the list have an item number followed by flags and parameter values. To change properties of an item, you have to use set command and specify name or number of the item.
Some lists have items with specific names assigned to each of them. Examples are interface or user levels. There you can use item names instead of item numbers. You do not have to use the print command before accessing items by their names, which, as opposed to numbers, are not assigned by the console internally, but are properties of the items.
Thus, they would not change on their own. However, there are all kinds of obscure situations possible when several users are changing router's configuration at the same time. Generally, item names are more "stable" than the numbers, and also more informative, so you should prefer them to numbers when writing console scripts. Item numbers are assigned by the print command and are not constant - it is possible that two successive print commands will order items differently.
But the results of last print commands are memorized and, thus, once assigned, item numbers can be used even after addremove and move operations since version 3, move operation does not renumber items. Item numbers are assigned on a per session basis, they will remain the same until you quit the console or until the next print command is executed. Also, numbers are assigned separately for every item list, so ip address print will not change numbering of the interface list. Since version 3 it is possible to use item numbers without running print command.
Numbers will be assigned just as if the print command was executed. You can specify multiple items as targets to some commands. Almost everywhere, where you can write the number of item, you can also write a list of numbers. Warning: Do not use Item numbers in scripts, it is not reliable way to edit items in scheduler.
Instead use find command. More info here also look at scripting examples. There are two features in the console that help entering commands much quicker and easier - the [Tab] key completions, and abbreviations of command names. Completions work similarly to the bash shell in UNIX. If you press the [Tab] key after a part of a word, console tries to find the command within the current context that begins with this word.
If there is only one match, it is automatically appended, followed by a space:. If there is more than one match, but they all have a common beginning, which is longer than that what you have typed, then the word is completed to this common part, and no space is appended:.My question is, what are they capable of?
Even 8MB should be sufficient. My primary question is what all is it capable of and how will it work. This looks like a really nice product and exactly what I have been looking for for a few devices. Easier than reset and re-configure for simple mistakes. A feature that I absolutely require though is the ability to access it remotely through the internet.
Reverse SSH perhaps? I would need to be able to connect to it from miles away, perhaps through a network I don't control. Put another way, if I have the WiFi client in the Woobm-USB setup to certain settings, can someone bring their smartphone into the area with the hotspot feature setup with the predefined settings, the Woobm connect to it and somehow make a connection outgoing that I can use.
Does this make sense? A data center that also provides WiFi access, have the Woobm connect to it, if I need to get access to a console, it can make an outgoing connection that I can use to access it. To be useful this is another connection option that needs to be implemented, that I haven't seen in any of the scarce documentation for the Woobm-USB. Sun Sep 17, pm Yeah I'd also like to ask about this product.
What it even is? Is it like routerboard with ROS powered via usb or is it more like just wifi card compatible with ROS devices with usb. Does ROS support other usb wifi cards as well? What Woobm really does and how ROS sees it. Can I use it as second wifi interface for wifi routerboards with usb?
Serial Port Usage
Or as wifi interface for non-wireless routeeboards? Paternot Long time Member. Sun Sep 17, pm It is a way to connect out of band, to a Mikrotik Router.
You plug it in the router's USB, it will be configured as a serial access. You connect your laptop, mobile, whatever, to the woobm via wireless. Now You have access to the console, or webfig, to the router. It is a tool to do maintenance, under certain conditions.
At least, that was the gist of it, to me. Mon Sep 18, am Paternot is right. There is no RouterOS on this device. It is a basic console over wireless adapter.
You connect to the AP it sets up, and when you telnet to it, you will have access to the parent device serial console. There is only telnet, and the basic Web interface it comes with there is a web based terminal. The device can also work as a wireless client, but the same still applies - connect to it's IP with Telnet, and you are in the serial console of the parent device. No answer to your question? How to write posts. Mon Sep 18, am That sounds pretty handy. Would be awesome if there were 4G and Ethernet versions.
Once I add in the mobile broadband card, case and antennas, my solution is a few hundred dollars, but that's still way less than OpenGear or CradlePoint's options.The screen just sits with a cursor in the upper left corner. Any ideas? For everyone in that boat, there is an easier answer:. Fix your firewall so that you can again connect by your method of choice. This information opened up the router enough to allow a LAN login for configuration via Winbox.
I believe you're overcomplicating things. What's the need for L2 bridging between the sites? You let unnecessary broadcast and multicast traffic travel across the interbranch WAN links. The Sophos firewall you have can do WAN failover just fine at the edge and it does site-to-site VPN just as good without any need for an extra networking device that can potentially fail. Layer-2 MAC access is very cool, though also very picky, especially with newer versions of Windows. CST is an IT service provider.
Next time use Safe Mode when playing with firewall rules. Also, you can always reset the device to defaults to avoid using the cable.

On every RouterBoard or other system you will have a RouterOS login prompt on serial0 the first serial interface. This is one of the ways to do the basic configuration on your RouterOS device after installation i.
There are other and more advanced uses for serial ports. I try to sum up those possibilities here. You can use RouterOS to access another device like a switch, for example that is connected through a serial cable. There's also a nasty workaround for sending text out over a serial port. Please note that there are some Caveats you should be aware of! Take your time understanding those limits to avoid strange things to happen when connecting a device to a serial port on a RouterBoard.
First you have to have a free serial port to use for this. Be sure to just disable the console rather than removing it, as RouterOS will recreate the console after the next reboot when you really remove it. Next you will have to configure your serial port according to the serial port settings of the connected device. Using the following command you will set your serial port to Baud 8N1.
Serial Port Usage
What settings you need to use depends on the device you connect:. Now's the time to connect your device if not already done. Usually you will have to use a null modem cable the same thing as a cross-over-cable for Ethernet. Now we're ready to go! This will give you access to the device you connected to port serial0.
Ctrl-A is the prefix key, which means that you will enter a small "menu" by pressing Ctrl-A. The Ctrl-A character will not be sent to your device! If you want to exit the connection to the serial device type Ctrl-Athen Q. This will return you to your RouterOS console.There are many ways how to use ports on the routers. Most obvious one is to use serial port for initial RouterOS configuration after installation by default serial0 is used by serial-terminal.
Menu lists all available serial, usb, Note: List of the ports are maintained automatically by the RouterOS. This submenu allows to specify directory where drivers for 3g modems can be uploaded and used.
If you want to access serial device that can only talk to COM ports and is located somewhere else behind router, then you can use remote-access. Note: By default serial0 is used by serial-terminal. Without releasing the port, it cannot be used by remote-access or other services.
