How would I, for example, send the command showport to ser2net? The ser2net control port is mapped to TCP port on the device running ser2net. Open a telnet session to that port from another device on the network that can see it.

It provides an Ethernet interface from the panel, which allows you to configure the panel over the network rather than having to connect directly to the panel.

It also allows you to connect other things in to the panel to provide remote control or get status information from it. The first problem is the price. Numerous other retailers have it for the same price although there are some second hand deals on ebay which are a bit better. First thing was to see what the serial connection is actually doing, and establish what the parameters for the serial connection are.

I used a serial port sniffer to identify this. I ran this whilst connecting to the panel with Wintex. I was hoping to see some comprehensible data but in fact it is clearly encoded. However, I was able to get the serial parameters out which are:. This is the first time I have ever seen a serial link which uses 2 stop bits — so maybe this is a sneaky trick by Texecom to get you to buy their product.

If so then it is fairly easy to get around. The next thing to do is to set up ser2net. It forms part of most Linux repositories, and the Raspberry Pi is no exception.

Then I have installed ser2net like so:. Then plug in the serial cable and it should be recognised and appear as a serial device. The next step is to set up ser2net to connect to the USB serial port and convert it to network frames. Restart ser2net to re-read the config file, and then you will have in effect a working equivalent of the COM-IP.

To make use of it you will need to IP address of the server running ser2net and the port number as above. The most obvious use of this is to use Wintex the Texecom configuration tool over the network. So far as I can tell this approach exactly replicates the function of the real COM-IP but at a fraction of the price, or indeed free if you already have a Raspberry Pi or a server lying around.

Great article… but how reliable to do you find the connection? Maybe I need to double check my wiring… have you experienced any connectivity problems?

If you are using a USB connection to the panel do you have any problems connecting directly? Very useful!

Do you know if the android app also works? What security is there? If you wanted more security at an IP level, could you perhaps use some rules on a firewall to control access to ports?GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Sign up. Branch: master. Find file Copy path. Cannot retrieve contributors at this time. Raw Blame History. This is an example configuration file for ser2net. A port number may be of the form [host,]port, such as If this is specified, it will only bind to the IP address specified. Otherwise it will bind to all the ports on the machine. It can be turned on later from the control port. This is most useful for using telnet. A zero value disables this function. Options, set the various baud rates.

The "remctl" option allow remote control ala RFC of serial-port configuration. See the man page for details. This takes the same escape sequences as banners. Note that the same device can be listed multiple times under different ports, this allows the same serial port to have both telnet and raw protocols.

You signed in with another tab or window. Reload to refresh your session. You signed out in another tab or window. It has the following. A port number may. If this is specified, it will.

It can be. It allow to use. The time in seconds before the port will be dis. A zero. Sets operational parameters for the serial port. Options. The "remctl" option allow remote control ala RFC.

The tw, tr, and tb options take a tracefile name. This will create a banner, if the banner name is given in the. This takes the.

Banners can span lines if.How fun was that?!? Recently a friend started studying for the CCNA exam and I started thinking that there had to be a way to use a Raspberry Pi to put the console ports on the network. Sure enough, there is a project called ser2net that does just that.

You will also need a USB to serial adapter. In fact we only need to add one piece of software to make this project work. Before we can configure ser2net we need to figure out where our serial adapters are listening. With this information we can configure our ser2net.

To edit it you can use nano with is already on your Pi. Inside you will find some default configuration lines at the bottom of the config file.

We can easily edit these to meet our needs. For my 4 port serial adapter, going to Cisco routers and switches which use 8N1 serial parametersmy file looks like this. So this configuration will let us telnet to our raspberry pi on the ports specified.

Those telnet sessions will be forwarded to our serial ports. You can use this setup for anything that has a serial connection. So anyone who knows the connection parameters telnet IPAddress Port will have access to the serial device listening. Justin is a Technical Alliances Architect for Zerto.

When not helping people learn about protecting their data from disasters, he is usually working on stuff in his home lab or spending time with his family. I was hoping that later versions would include include UDP. Consider that if your computer has an RS port. You can open that port and connect a cable to it — or not. If there is no cable, the data sent to that port goes nowhere, and nothing comes in to that port.

But when the cable is connected to another device — data can flow. Let me see if i can get it to compile.

This was very usefull, thank you. To update your Pi and install ser2net use the commands below: sudo apt update sudo apt upgrade -y sudo apt install ser2net -y Serial Port discovery Before we can configure ser2net we need to figure out where our serial adapters are listening.

Related 3. Hot Network Questions. Question feed.The program comes up normally as a daemon, opens the TCP ports specified in the configuration file, and waits for connections. Once a connection occurs, the program attempts to set up the connection and open the serial port. If another user is already using the connection or serial port, the connection is refused with an error message.

This may be specified multiple times for multiple lines. This is just like a line in the config file. This disables the default config file, you must specify a -c after the last -C to have it read a config file, too.

This is useful for running from init. This is most useful for debugging purposes. A pidfile is not created by default, you must specify this to create one. This option sets the IOS version of setting the baud rates. The default is RFC's. A port number may be of the form [host,]port, such as If this is specified, it will only bind to the IP address specified for the port. Otherwise, it will bind to all the addresses on the machine.

This way, it can be used from inetd. If no port is given, all ports are displayed. This can produce very wide output. Only one direction may be monitored at a time. The type field may be tcp or term and specifies whether to monitor data from the TCP port or from the serial port Note that data monitoring is best effort, if the controller port cannot keep up the data will be silently dropped.

A controller may only monitor one thing and a port may only be monitored by one controller. If conflicting options are specified, the last option will be the one used. Note that these will not change until the port is disconnected and connected again.

Options, set the various baud rates. These do not stay between connections. A file with another name or path may be specified using the -c option, or individual config lines may be specified with the -C option. Otherwise, it will bind to all the ports on the machine.This will bring serial communication to the wireless network. This will only work if the controller supports a lan connection where it will use 'telnet like' communication to the other end.

Domoticz has support for a few of those LAN gateways. This may change in the future as it depends on Arduino ESP core 2. Next use the device tab on the ESP Easy webinterface and create a new task by editing one of the available tasks. Select "Serial Server" from the dropdown box. Enter the serial port settings that match with the target device and select the TCP port that the remote controller uses to connect to this serial server.

That should be all. You can test communication using the good old telnet tool, just connect to the ESP IP address and start typing. Characters should appear on the serial port. There's an option to connect a GPIO pin to the target device reset pin must be active low. Once connected, the ESP will reset the target device during it's own boot stage.
