Intercept serial port communication
Posted on 2001-08-06
Because I want to understand the protocol in which an application "talks" to external hardware, I need to have a program which intercepts the "talking" and dumps it to a file.
The program must sit and wait until another program writes or retrieves data to or from the COM1: port (it has to run on a Windows 2000 machine).
Is this possible in VISUAL C++ (or in any way at all?). If such a program already exists, please say where I can get it!
Thnx in advance,
