/* This is like remote.c but uses the Universal Debug Interface (UDI) to
|
24 |
|
|
talk to the target hardware (or simulator). UDI is a TCP/IP based
|
25 |
|
|
protocol; for hardware that doesn't run TCP, an interface adapter
|
26 |
|
|
daemon talks UDI on one side, and talks to the hardware (typically
|
27 |
|
|
over a serial port) on the other side.

- Originally written by Daniel Mann at AMD for MiniMON and gdb 3.91.6.
|
30 |
|
|
- David Wood (wood@lab.ultra.nyu.edu) at New York University adapted this
|
31 |
|
|
file to gdb 3.95. I was unable to get this working on sun3os4
|
32 |
|
|
with termio, only with sgtty.
|
33 |
|
|
- Daniel Mann at AMD took the 3.95 adaptions above and replaced
|
34 |
|
|
MiniMON interface with UDI-p interface. */
