Serial Port Sniffer Windows 7

I use a Java application to interact with the device and I want to have a native app that allow me to see the exchanged frames (both ways), but I can't find any software for that in Windows 7 x64. Is there any software to sniff ir just redirect a COM port received and trnasmitted messages?

Can anyone recommend any good Com port monitor tools, like Portmon, which also work on Windows x64? Ideally something open source / freeware would be good.

The only one I have found for x64 is 'Advanced Serial Port Monitor,' which is really quite good. Not free, priced at $60 USD for a single user license. There is a 15-day trial. Honestly, I've been hoping (for quite a while now) that Mark R. would release a 64-bit version of portmon.

Old question, but very relevant. While serial ports may be gone from consumer devices these days, it is still very much used in industrial hardware, point of sale hardware, radios, etc. In my case I was trying to capture a communications session from a configuration software tool for some hardware equipment.

In the end I found a commercial app from Eltima Software called Serial Port Monitor which did the trick for me on Windows 7 x64.

I've looked around quite a bit, but I have yet to find a free way to monitor a serial port (without opening or blocking it from other applications), that works on Windows 7 64-bit.

Even Microsoft's own Portmon does not work. A few posts have talked about running it in compatibility mode, but it doesn't work for me. I've tried compatibility mode for Windows XP service pack 2 and 3 (the only ones available on the drop-down list), and neither allow it to function.

So yeah, is there any way of monitoring a serial port for Windows 7 64-bit?

I just tried Advanced Serial Port Monitor. 'Spy' mode does just what you want.

It's only free to try. However, you have to pay for a permanent solution.

A workaround I have used in the past when I was in the exact same situation as you was to use a 32-bit VM.

It's not the greatest solution, but it does work and has no cost (other than any costs associated in setting up your VM Environment).

Alldata free trial. If you have another computer, I recommend running a POSIX OS and using socat to 'pipe' the data from one port to another while logging the traffic. This is basically like a hardware-based solution, but it's using general purpose hardware instead of something special. e.g. something like this:

sudo socat -x -v -d /dev/ttyUSB0,b115200,rawer,cr /dev/ttyUSB1,b115200,rawer,cr

What's really neat about this program is that it's super flexible as far as what you can connect to what. You can use TCP/IP sockets, files/streams, etc. transform baud rates, change line endings, etc. Introductory article (dated 2009 but still useful) is available here.

Edit: Just to clarify, instead of having a hardware configuration like this:

Main computer serial port <--> Device serial port

Serial Port Scanner Windows 7

It'd be like this:

Main computer serial port <--> sniffer computer serial port 1Device serial port <--> sniffer computer serial port 2
