Sending ASCII strings to a device on your network using TCP/IP involves knowing some knowledge about C++/Visual Basic because there isn't a compiled tool to do this. You will first need to understand what socket stream the device uses and what ports are open for the communication and then code your application using System.Net.Sockets.TcpClient, System.IO.BinaryReader/BinaryWriter and System.Text.Encoding.ASCII as libraries. The way you implement this code is only up to you and its only based on your needs with the device.
