Need to understand the serial communication protocol between a USB device and PC, that uses serial over USB communication. I was planning on using a software based approach for serial port sniffing / monitoring / logging the serial communication.
My constraint is availability of PCs running Windows 7 64-bit only, and none of the methods I have come across work on this setup. Here are some that I've tried:
- How can I monitor a virtual serial port in Windows 7?
- I'm looking for serial port monitoring software
- RS232 Packet Sniffer
- Is there a free way to monitor a serial port on Windows 7 x64?
Looking for alternative ideas, approaches ? Hardware based approach would not be my first choice, but anything that can be done at a low-cost, or better still -- DIY, I'd love to hear more.
