ComLogger

If you ever wanted to log serial data in a very easy way, this is what you need.

State:

Fully functional - Microsoft Windows - download

Very easy to use (HyperTerminal is so bad)
Run in TEXT mode for catching debug texts
Or can be run in BINARY mode, so you can also analyze any binary serial protocol.
Timestamps are added to each line to better analyze the results
NTP time synchronization for very accurate timestamps
Selectable fonts and colors
Export of log files
DTR detection
Automatically detects available serial ports.
Completely free (but no source code as I developed it for my employer)

Known bugs: When the log file becomes VERY large, it will stop functioning.....
