You're either one of two people. The person writing that simple device handler or the 
person writing a full blown file system. Which ever you are, you're going to face a 
problem possibly worse than the actual coding of the handler itself, testing it in a real 
world situation. Forgetting that for a moment, testing the code at all. As you know, 
similar to a library or a device their is not an easy no standard way of testing a device 
handler in a debugger and single stepping through it. That is, until now. I recently faced 
this same problem, and so started searching for programs that would help. I found none. 
So then I started searching for solutions to the problem, experimented with my ideas and 
came up with this program. Which really works! I have written a program that will allow 
you to load your code into your usual debbuger and handle the other task, dos packets. 
You can happily debug away on your handler and communicate with it normally as you 
would with dos as TestHandler will automatically take care of this set up for you. Now out 
can get a grip, get on with the job, and not worry about putting fiddly in-line messages in 
your handler and coding blind.
