- over a serial port) on the other side.

- - 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
- file to gdb 3.95. I was unable to get this working on sun3os4
- with termio, only with sgtty.
- - Daniel Mann at AMD took the 3.95 adaptions above and replaced
- MiniMON interface with UDI-p interface. */
