Serial Port Redirector (Serial to Ethernet Connector) is a software tool that enables you to redirect up to 500 serial port devices over network (Internet or LAN). A single COM port can be accessed by multiple computers in the network, no matter where the port is actually located. With Serial Port Redirector by Eltima there is no problem of working with remote serial devices - be it a modem or any other kind of equipment that uses serial ports for communicating with a PC. Remote and virtual serial ports and devices will be treated by your apps as if they were plugged directly into your machine.

Also available on Linux OS and Windows Mobile

With Serial Port Redirector you can

Redirect serial ports over TCP/IP network (Server)

Server listens for incoming connections from clients and redirects local COM ports – either real or virtual – over Ethernet. Any application that can initialize outgoing connection to TCP/IP server can be a client. A single COM port can be redirected to multiple clients at the same time, and each of them can transmit data to their local serial port, while Serial Port Redirector will gather all the data on the server.

Connect to serial ports remotely (Client)

Once a client connection is created, data transmitted by a local serial port is redirected to the remote server over TCP/IP protocol. You need to specify the IP address (or the network name) of a remote server and TCP port to connect to, it is not required to install Serial Port Redirector on the remote server. Once your machine and a remote server are connected, your local serial port will receive all the data sent from the remote end.

Utilize UDP for data transfer

Serial port data can be redirected over UDP/IP transport protocol and broadcast over a local network. Serial port redirector installation is not required at the remote end. You can choose either RAW data transmission algorithm or Telnet (RFC 2217) as a protocol for transmitting the data.

Serial Port Redirector for Linux OS

COM Port Redirector (Serial to Ethernet Connector) is a cross-platform solution, it now has a command-line version for Linux OS. You can designate a Linux machine as a server and Windows machine as a client, or the other way around. Serial Port Redirector for Linux supports data transmission over UDP.

What customers say

Xuehui Li, Product manager

It is just what we need! COM Port Redirector is bounding our hardware together. Now, we don’t have to pay the extra cost for maintenance and upgrading of our virtual COM drivers. It is the perfect solution for us!

Steven Bradshaw, Vice President of CVARS (Canada)

I settled on Serial Port Redirector because it did everything I wanted it to do. It saves me a lot of time and headache.

Claudio Corniani, Electronic Engineering Manager (Italy)

We choose COM Port Redirector product because of greater integration of virtualization of the serial ports, like physical devices.
