  - Originally written by Daniel Mann at AMD for MiniMON and gdb 3.91.6.
  - David Wood (wood@lab.ultra.nyu.edu) at New York University adapted this

-       with termio, only with sgtty.  Because we are only attempting to
-       use this module to debug our kernel, which is already loaded when
-       gdb is started up, I did not code up the file downloading facilities.  
-       As a result this module has only the stubs to download files. 
-       You should get tagged at compile time if you need to make any 
-       changes/additions.
