What is serial over LAN? It is a software solution that lets you communicate with a remote COM device as if was directly connected to your computer. These software tools enable you to share serial ports over LAN as well as use serial devices with computers that are not equipped with serial ports. In this article, we’ll tell you about the best software and hardware solutions to help you share your valuable serial devices over LAN easily and effortlessly.
Here's how you can connect to a serial port over LAN with this efficient app:
That's it! Now you can enjoy full access the functionality of a remote serial device as though it were connected directly to your PC. No additional hardware or cables are required. Completely software serial to LAN solution lets share an unlimited number of COM ports between multiple computers at a time. In addition, you can create cross-platform connections between Windows and Linux platforms.
TCP/Com program is a basic solution suitable for accessing serial devices as well as RS232 to LAN conversion implementations. Some of the connectivity tasks it can resolve include: turning a computer into a Serial Device Server; communicate over the network with any serial device or application; enact remote control of Serial ports as if they were local; mapping of TCP/IP interfaces; split data from a single physical COM port and send it to multiple serial apps. It runs on versions of the Windows OS from 98 to Windows 10 (32- and 64-bit).
Network Serial Port Kit is another software tool designed for COM port over LAN sharing. The serial over IP application makes a physical serial ports accessible to other network-attached computers. This lets you connect your machine to a remotely located COM device simply and easily. The program fully emulates serial port internals so that the virtual ports look and function as if they were physical ports.
Network Serial Port Kit is supported on the Windows 32- and 64-bit operating systems and lets you share and access any number of serial devices.
Serial-TCP/IP is an application that enables serial on LAN transmission and makes your current TCP/IP control software available from remote locations. Its built-in "Ping", "Resolve IP Address / HostName", "COM Port State LEDs", and "Data Logging" options facilitate analysis of your TCP/IP network and COM devices. As with the other solutions discussed, this tool makes the testing and debugging work of serial software and hardware developers easier. A limitation of this software is that it only runs on Windows 8, 7, Vista, and XP (32 and 64 bits).
Advanced Virtual COM Port is a communications application that offers COM port to LAN functionality as well as the ability to create virtual serial ports. Your apps will treat these ports as if they were physical interfaces as they are created with all parameters and functionality fully emulated. You can dynamically create, remove, and monitor up to 255 virtual ports with no need of rebooting your machine.
Advanced Virtual COM port supports Windows 2000 - Windows 8.1 (32 and 64-bit) and Windows Server 2012 R2. It also supports Windows CE versions: CE 5.0 (x86), CE 5.0 - 6.0 (arm), Mobile 2003 SE, and Mobile 5.0 - 6.5.
A vast variety of modern day equipment is designed to connect to a PC with the help of a standard RS232 cable. This way of communication is typical for today’s POS hardware (barcode scanners, receipt printers, payment terminals), automated industrial lines, specialized laboratory equipment (electrochemistry meters, spectrometers, spectrophotometers) and many other universal devices and instruments.
For many years RS232 has remained a standard protocol for the data transmission. Being a cost-efficient and reliable solution, this port is used by a great number of current hardware and software products. It serves as a basic way of communication for hundreds of serial apps. Considering the ubiquity and flexibility of the interface, the need for this efficient solution is expected to continue well into the future.
On the other side, a typical RS232 connection is established via a regular cable that enables point-to-point communication. This method of linking devices is not always convenient given the distance limitations of the hardware cable. Besides that, connecting every new peripheral to a computer requires a separate cable to be run to a separate serial port of the machine. Therefore, your PC should fit as many COM interfaces as many devices you want to connect to. This not only leads to cable clutter hanging down from the back of your desk but also makes it difficult to attach the device to more than one PC.
Luckily, there are some dedicated hardware and software solutions designed to help you overcome all the abovementioned inconveniences.
A serial port is one of traditional I/O interfaces used by a computer to exchange data with another PC or a serial-based device one bit at a time. Back in the old days, serial ports served for connecting a computer with printers and external modems and nowadays the interface helps to establish a communication between scientific instruments, industrial applications, shop till systems, etc.
If compared with a parallel female interface, a serial port has a male connector. In the system, serial ports are represented as COM1, COM2, COM3, and so on. Each COM interface has its unique position in the technical scheme of a PC and represents an input/output (I/O) address as well as an interrupt request (IRQ) level. That means a printer or a keyboard can transport data to a computer by using the I/O address.
Serial interfaces are able to work in a full-duplex mode, that is transport data in both ways (incoming and outgoing) at a time.
The most common standard for a serial port is RS-232. The devices that communicate via this standard are usually referred to as the DCE (data communications equipment) and DTE (data terminal equipment). The DCE talks to the DTE via serial connectors of different types. The most widespread ones are DE-9 (9-pin) or DB-25 (25-pin) ports.
Based on your requirements, one of these COM to LAN applications or hardware will solve your problem. Some of them are free, and some carry a cost (if we talk about hardware connectors). Keep in mind, that the benefit of using paid software is that you will get program updates and technical support. The software is definitely easier to use and no need in long cords. This can be critical in helping you use the software if you run into any potential issues. So, the decision about the app choice totally depends on your particular situation, and the requirements you have for the software performance. All these apps are a good helper in solving serial over LAN issues.
