AAARGGGGHHHHHHHH!!!!!!  Okay, once more with feeling, Communications Toolbox.
Connection Manager.  Communications Manager is an evil creation of that other
computer company.

What the Connection Manager does is to abstract the application from the low
level stuff.  Underneath the manager, sits connection tools that handle the
low level stuff for you.  

How it works:  
The app makes a call to read or write data.  The manager relays this to the
current tool, which takes care of talking to an associated driver.  The choice
of the tool is left up to the app, and in some instances, the user. 

The big win is that the same code will work regardless of whether you're using
a Serial Connection tool, an ADSP connection tool, or the newly announced
Telepathic Conn tool.
