| 22 | talk to the target hardware (or simulator). UDI is a TCP/IP based |
| 23 | protocol; for hardware that doesn't run TCP, an interface adapter |
| 24 | daemon talks UDI on one side, and talks to the hardware (typically |
| 25 | over a serial port) on the other side. |
| 26 | |
| 27 | - Originally written by Daniel Mann at AMD for MiniMON and gdb 3.91.6. |
| 28 | - David Wood (wood@lab.ultra.nyu.edu) at New York University adapted this |
| 29 | file to gdb 3.95. I was unable to get this working on sun3os4 |
| 30 | with termio, only with sgtty. |
| 31 | - Daniel Mann at AMD took the 3.95 adaptions above and replaced |
| 32 | MiniMON interface with UDI-p interface. */ |
