I am currently working on a project where I communicate with hardware via a com port on its respective pc(win xp or 7) It is a fairly large project and sifting through the log file can be a bit of pain.

This is my current setup. I use putty to do the actual serial communication, and write it to a log file. Then using MinGW Msys I filter it using

tail -f "puttyLog" | grep -i "search term"

Is there a better way to do this? I mean specifically filtering the input in realtime.

Not that mine is terrible, but it still involves having to read from a log and sometimes there have been hangups where it will be delayed for a minute or 2. I have used software in the past with a main io window and then internal filter panels, but can no longer remember or find it.

You can try using SOL (serial over lan) connection. It will be like local one. Here is something for data transfer you can check. Socat
