Im trying to emulate an existing program which writes to the serial port.

I have the output of what the program does (which works) and what program does (which doesnt work)

I can only see one difference between them and fc.exe doesnt help as the timings are different.

So heres your task - what differences are there between the following 2 blacks of code (ignore the second column)

Working:
Code:

Second one is missing,

0.08334914 LED.exe IOCTL_SERIAL_WAIT_ON_MASK Serial0 CANCELLED

If that matters :)
