![]() ![]() The performance of a COM port redirector is determined by both its implementation and the network it uses to reach device servers. The redirector GUI typically also includes displays of virtual COM port activity and various diagnostic aids. The COM port redirector then begins relaying the application data stream between the virtual COM port and the device server.Ī redirector will typically permit creation of many (at least 256) virtual COM ports, but simultaneous use of hundreds of ports is often practically limited by a number of factors, including the memory and processor requirements of the redirector, limits on operating system resources, and the performance of the network stack.Ī redirector for the Windows operating system is typically configured using a control-panel style graphical user interface for creating virtual COM ports, configuring settings for individual COM ports, and configuring global settings affecting all COM ports. When the application opens the virtual COM port, the redirector makes an IP network connection to the device server at the specified IP address and TCP/UDP port number that corresponds to the remote device on the server. These issues are described in the Technology section below.Īpplications use a COM port redirector through one or more virtual COM ports that the redirector creates, as configured by the user. The main challenges arise in two other areas: the network connection to the device server and the behavior of the device server. A virtual COM port itself is a relatively simple software mechanism that can be implemented by driver software similar to that of a conventional COM port driver. Serial Port Redirector for Linux supports data transmission over UDP.The purpose of the redirector is to make the virtual COM port exhibit behavior that closely resembles that of a "real" COM port, i.e., a COM port driver for local serial port hardware. ![]() You can designate a Linux machine as a server and Windows machine as a client, or the other way around. You can choose either RAW data transmission algorithm or Telnet (RFC 2217) as a protocol for transmitting the data.ĬOM Port Redirector (Serial to Ethernet Connector) is a cross-platform solution, it now has a command-line version for Linux OS. COM Port Redirector installation is not required at the remote end. Serial port data can be redirected over UDP/IP transport protocol and broadcast over a local network. Once your machine and a remote server are connected, your local serial port will receive all the data sent from the remote end. 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 a client connection is created, data transmitted by a local serial port is redirected to the remote server over TCP/IP protocol. 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.Ĭonnect to serial ports remotely (Client) Any application that can initialize outgoing connection to TCP/IP server can be a client. Server listens for incoming connections from clients and redirects local COM ports - either real or virtual - over Ethernet. Redirect serial ports over TCP/IP network (Server) Whether you're looking at redistributing our Serial port redirection engine as a part of your product or considering Serial over Ethernet software for an enterprise-wide deployment, we offer flexible and affordable corporate solutions designed to meet your needs. Remote and virtual serial ports and devices will be treated by your apps as if they were plugged directly into your machine. With COM Port Redirector by Electronic Team 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. A single COM port can be accessed by multiple computers in the network, no matter where the port is actually located.
