Somewhere long ago I remember a tool that would display TCP IO but I forget its name. Does anyone know of a tool that does this. I am working on a pair of apps, a TCP send and a TCP receive so I can run remote apps within my local network from a single send app. Any help here would be highly appreciated.

Maybe Wireshark? https://www.wireshark.org/ (https://www.wireshark.org/)

TcpLogView :
QuoteTcpLogView is a simple utility that monitors the opened TCP connections on your system, and adds a new log line every time that a TCP connection is opened or closed. For every log line, the following information is displayed: Even Time, Event Type (Open, Close, Listen), Local Address, Remote Address, Remote Host Name, Local Port, Remote Port, Process ID, Process Name, and the country information of the Remote IP (Requires to download IP to country file separately.)

LiveTcpUdpWatch :
Quote
LiveTcpUdpWatch is a tool for Windows that displays live information about all TCP and UDP activity on your system. Every line in the main table of LiveTcpUdpWatch displays the protocol (TCP/UDP/IPv4/IPv6), local/remote IP address, local/remote port, number of sent/received bytes, number of sent/received packets, connect/disconnect time (For TCP only), and the process (ID and path) responsible for this activity.

CurrPorts :
QuoteCurrPorts is network monitoring software that displays the list of all currently opened TCP/IP and UDP ports on your local computer. For each port in the list, information about the process that opened the port is also displayed, including the process name, full path of the process, version information of the process (product name, file description, and so on), the time that the process was created, and the user that created it.

SysInternals had a tpcview tool - not sure if its still available or part of the suite of tools
Hi fearless
You can still download it at https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview (https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview)
I have already got it. Long ago I remember something that worked really well but I forget its name. "tcpview" works OK but its hard to keep track of a single app when there is so much other stuff being read as well.
I found something that works, its called Udp Test Tool. The send app seems to work fine. Now I have to decypher why the receive app prevents the send app from working and vice versa.
I know you guys don't do serial/Rs485/USB type stuff
that often - but if you want all that + parallel on top of TCP/IP
RAW/protocols packets - have a look at IO Ninja (Windows + Linux)
probably more of an industrial software tool. I get away with a
logic analyser (cheap banggood 24 dollar probe) hardware usb
thing myself.
