Any free application to redirect serial communication to TCP/IP?

Question

Please can anyone suggest a free application which creates virtual serial ports and any traffic on that port is redirected to given TCP/IP address?

Answer 1

If this is for Windows, then see HW VSP3 - Virtual Serial Port

HW VSP is a software driver that adds a virtual serial port (e.g. COM5) to the operating system and redirects the data from this port via a TCP/IP network to another hardware interface, which is specified by its IP address and port number.

Main Features

• Free, unrestricted Virtual Serial Port driver for any TCP/IP devices
• Compatible with Windows 2000, XP (Win 98, NT) and Windows Vista
• Runs as a standalone application, or as a NT service suitable for servers
• Option to start at Windows startup and minimize to System Tray
• Single-port (free) and multi-port (commercial) version
• Supports RFC 2217, allowing to change remote serial port parameters (such as speed, parity, stop bits) over TCP using NVT
• VSP driver typically operates as a “TCP client”; however, it can also be used as a “TCP server” (useful for GPRS applications)
• Configuration stored in an INI file
• Configuration protected with a password
• Supports UAC (User Account Control – user switching in Windows XP and Vista)
• This software is FREEWARE, as long as you comply with the license terms and conditions

Answer 2

com0com, Null-modem emulator, also includes COM to TCP redirection.

The Null-modem emulator can be used to provide serial interface for COM port redirectors. For example, with the com2tcp ( COM port to TCP redirector, part of the com0com project ) you can communicate via serial interface with the TCP/IP servers.

I just found TCPCOM32 and there are also some other projects at SourceForge which are doing such a thing.

Also, what operating system?
