ComMonitor
Com Monitor is a small but complete utility for playing and testing with TCP
socket connections.
It is also useful for testing connections with devices other than a PC: PLC or COM server or any other device that uses TCP Sockets.
ComMonitor is licensed under the
MIT license
and in addition to the useful socket connections feature, it is
also intended as a demonstration piece of software for
developers who are in the beginning to write desktop
applications in WPF.
You can find the source code on
GitHub.
