Hello,

I like to find out how a certain windows .exe application modifies data before sending it to the serialport.

I run some disaasemblers but they only show a disassembled file.

I'm looking for some Windows tool where you can execute the executable and step through the code instruction by instruction.

I searched Internet a lot but don't know where to start.

All tips are welcome.

Regards,

Henk

Two of my favorites is GDB, and especially OllyDbg.

GDB uses CUI, while OllyDBg uses GUI, so it's much about taste, but of course there's other differences too.

When using OllyDbg you have to now a lot about Assembly Programming, and you don't have to know so much about it, when using GDB.

Instead of I'm just talking, I'll give you some links:
Index of /gnu/gdb
OllyDbg v1.10

Hey thanks!
OllyDbg is what I'm looking for.
Now the real work starts...
