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