Free Serial-TCP (More Than Just A Device Server)
-
In the past two decades, legacy serial communication protocols such as Modbus have merged rapidly with modern TCP/IP communication, yielding benefits including widely available infrastructures and greater distance, reliability, and speed. The Serial-TCP program (more than just a Device Server) bridges your existing Serial COM port and TCP/IP without the need for changing existing protocol. It works seamlessly and transparently, just like passive RS232 / RS485 / RS422 converters, repeaters, and hubs, while the difference is that one requires installation of cables and converters with limited distance; and the other simply makes use of the existing computers and networks with an unlimited transmission distance
