22 | /* This is like remote.c but uses the Universal Debug Interface (UDI) to | |
23 | talk to the target hardware (or simulator). UDI is a TCP/IP based | |
24 | protocol; for hardware that doesn't run TCP, an interface adapter | |
25 | daemon talks UDI on one side, and talks to the hardware (typically | |
26 | over a serial port) on the other side. | |

28 | - Originally written by Daniel Mann at AMD for MiniMON and gdb 3.91.6. |
29 | - David Wood (wood@lab.ultra.nyu.edu) at New York University adapted this | |
30 | file to gdb 3.95. I was unable to get this working on sun3os4 | |
31 | with termio, only with sgtty. | |
32 | - Daniel Mann at AMD took the 3.95 adaptions above and replaced | |
33 | MiniMON interface with UDI-p interface. */ | |
