- file to gdb 3.95. I was unable to get this working on sun3os4
- 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.
