Redirect serial port data with
COM Port Redirector
COM 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 COM 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 COM 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. COM 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.

FAQ about COM Port Redirector
A virtual COM port is a type of serial port redirector that can operate independently of specialized network software. You can create multiple virtual interfaces on a single computer allowing serial software applications to talk to each other directly without the need for named pipes or other methods of communication.
The creation of a virtual port is not very complex and can be carried out by software tools similar to those that implement physical serial port drivers. The functionality that is added by an Ethernet COM port redirector is the ability to fully emulate physical interfaces to enable communication with peripheral devices that are locally attached to a computer.
With Serial to IP Port Redirector, you can simultaneously have up to 256 virtual COM ports active on a machine. In practice, the number of interfaces your system can support is influenced by its physical capabilities. Factors like the network bandwidth that is available or the amount of free memory on the machine may reduce the number of connections that can be active at one time.
On computers running Linux, network serial port redirection is handled by an operating system daemon. The role of the daemon is to scan for attempted connections from other instances of Serial Port Redirector, transfer data between the network and serial interfaces, and to create outgoing connections when they are required.
