I think there's an easier way.  GDB has a command to call any function in 
your program with certain arguments.  Write a function that displays the 
contents of your private transfer buffer (I presume that is what you want 
to do, right?), add it to your program, relink, then call it with the 
necessary selector/offset values when the program stops at a breakpoint.
