v2.00

04/6/2025

Complete re-write of the software, starting from ground up.
Adding more features required us to limit the operating system support.
This version 2.00 only supports Windows 7, 8, 10, 11, and newer. and Windows Server 2008, 2011, 2012, 2019, 2022, and newer.
Removed UDP support - it didn't work on new versions of Windows.
Added detection of HTTP requests and responds with valid HTML.
Raw TCPIP sockets now sends a sucess message "Welcome to the Port Listener Server on port [portnumber]" when a client has connected.
Added option to include a Timestamp in the log.
Add the option to clear the log each time it starts listening on a port.
Added Windows System Tray support.
Command line passing of the port number now auto minimizes and starts listening on the port.
Corrected the min and max port numbers to align with new Windows restrictions.

Thanks to our generous downloaders who paid for this update!

v1.03 has reached its end of life. You can still use v1.03 on older Windows systems, but we will not be updating or maintaining the code.
