21 | /* This is like remote.c but uses the Universal Debug Interface (UDI) to |
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. | |
5140562f JG |
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 | |
157ea89d | 30 | with termio, only with sgtty. |
15ee4caa | 31 | - Daniel Mann at AMD took the 3.95 adaptions above and replaced |
5140562f JG |
32 | MiniMON interface with UDI-p interface. */ |
