vb question

I have an app that is somehow getting lost someplace, and I can't figure out what is going on.

I enter a function, have a stop at the end and sometimes my program never hits the end.
It isn't freezing, I just don't know what step it is on.

I am communicating via a com port with another machine, and if I step through the program, I can't replicate it.

Pretty much, I was wondering, is there any way to figure out the last few functions where the program executed?

Is there a way to trace the path of functions?

You're best bet is to simply start spattering your subs/functions with either Debug.Print "you are here..." or use MsgBox "you are here..."
