FlexiHub: the COM port redirector software

FlexiHub is a desktop app that holds a special place among software COM port redirectors available today. The program can easily connect your PC to a remote serial device no matter the distance between them. FlexiHub’s user base is largely made up of folks who need to redirect COM port over Ethernet, WIFI, or the Internet fast and securely. The nice thing about the app is that it protects all communications with advanced traffic encryption, so you don’t have to worry that your sensitive data will be lost or intercepted.

In addition to serial peripherals, FlexiHub can easily share USB devices as well. With the solution, you’ll have no problem redirecting your devices to a virtual environment.

FlexiHub is fully compatible with VMWare, ESX, Citrix XenDesktop, Microsoft Hyper-V, Windows Virtual PC, and QEMU virtualization software.

How to redirect serial port:

First of all, you'll need to register a FlexiHub account.

One more thing that makes FlexiHub a really great COM port redirector is the speed of connections. The app’s traffic compression feature allows transmitting serial data significantly faster. Users find this especially helpful when interacting with certain types of devices that originally communicate data in an uncompressed format.

Device Isolation for Multi-User Systems
FlexiHub lets you to isolate COM port devices per session and your COM port will be visible only to you and available only in your user sessions.

On top of that, if two users are logged into the same account, they can start communicating with comments and reactions via a convenient FlexiChat - one of the latest improvements to the program. FlexiChat is available in the Windows version of the app.

Serial to Ethernet Connector: redirect COM port over LAN

Serial to Ethernet Connector is a software solution used to redirect traffic from serial ports over a network. It enables you to access the COM port along with its attached device from any remote computer on a TCP/IP, LAN, Wi-Fi or any other IP-based network. The full functionality of the attached device is obtained by the remote user when employing this communication utility.

The software features an intuitive user-interface that makes it easy to switch up to 500 virtual ports that the tool supports. Three types of connections can be established using this versatile program. A server connection is used to provide incoming requests to access a shared serial port. The software allows clients to connect to a shared COM port via a network. Data can also be exchanged between interfaces using UDP.

Serial over LAN software is the most efficient way to access serial ports remotely. Here are the simple steps required to use the tool.

Step-by-step guide to use Serial port Redirector from Eltima

  1. Download Serial to Ethernet Redirector (aka Serial to Ethernet Redirector) and install it on the computer that will share a COM port as well as any computer that needs to access the shared serial interface.
  2. Choose “Server connection” in the application on the computer that will share the port. Customize the connection settings and then click "Create connection" in the main window.
  3. Open local serial port.
  4. Create a “Client” connection on a computer that will access the shared local port. The remote hostname and port number must match what you have configured on the server that will share the interface.
  5. Click 'Connect' on the remote machine to establish a connection with the shared port. You now have access to the port and any attached devices as if they were directly attached to the remote computer.

That’s all there is to it. With those simple steps, you can remotely access serial devices over a network without any extra hardware or configuration. The remote connectivity allows you to manage the remote device as if it were locally attached. The application supports both the Windows and Linux operating systems.

Serial Port Redirector (Fabulatech)

The Serial Port Redirector from FabulaTech allows users to easily access and share an unlimited number of serial devices over a network. It redirects serial data transmissions from local or remote devices to the network where they can be accessed by any connected machine. The COM port redirector for Windows supports sharing serial devices on machines running either the 32 or 64-bit versions of the OS. Connectivity is provided by virtual serial ports that replicate the full functionality of physical interfaces.

Com Port Redirector

Virtual COM Port Redirector is a software solution that enables serial ports to be shared over a network. Windows computers can take advantage of virtual serial port mapping to connect to serial devices located anywhere as long as they are connected to the same network. After establishing the remote connection, full control of the device can be taken as if the peripheral was physically attached to the computer.

Some of the features of Virtual Com Port Redirector include:

  • Communication is enabled between serial-based programs and remote COM interfaces and devices.
  • Serial communication can be established with no distance limitations.
  • Serial devices can be controlled remotely over any type of IP-based network.
  • Signal control lines can be monitored efficiently.
  • Serial port traffic can be observed, logged, and analyzed.

There are many COM port redirector solutions on the market and you should be able to locate one that works for your situation. Some free solutions may be appealing but you need to keep some things in mind when going in that direction. A paid solution will offer technical support and program updates that can be the differentiating factors in allowing your project to be successful.

Frequently Asked Questions

COM Port Redirector is an application that enables users to connect to serial devices remotely over an IP-based network. The software works by establishing virtual serial ports bound to a specific IP-address and TCP-port to which it forwards data from a physical serial interface.
A virtual serial port redirector enables the user to create virtual serial interfaces that are independent of dedicated network software. Multiple interfaces can be created on a single machine, allowing you to use more devices simultaneously than the number of physical ports on the computer. Serial devices can communicate with network-attached machines anywhere in the world, adding value to your peripheral equipment.
The network redirector uses virtualization to give client machines the appearance of having a direct connection to resources physically located on a remote physical server. These resources may be files or peripheral devices such as printers or scanners. The COM redirector act as a bridge between the local and remote computer and redirects serial data transmission in both directions. Through the redirection of requests made from the remote client machine, it is provided with the same level of functionality achieved with a direct connection when accessing the resource on the server.

Network problems can get in the way of successfully transferring data remotely. Serial redirector software attempts to satisfy requests several times before generating an error message to provide transparency regarding the access to the remote resources. It will send an error message to the client if the connection cannot be established.

There are two options available when you need the ability to connect to devices remotely over the Internet, LAN or any IP-based network. You can choose between hardware and software solutions to create a connection. Here are some advantages and disadvantages of both solutions for you to consider as you make your choice.
