-/* This file was derived from remote-eb.c, which did a similar job, but for
- an AMD-29K running EBMON. That file was in turn derived from remote.c
- as mentioned in the following comment (left in for comic relief):
-
- "This is like remote.c but is for a different situation--
- having a PC running os9000 hook up with a unix machine with
- a serial line, and running ctty com2 on the PC. os9000 has a debug
- monitor called ROMBUG running. Not to mention that the PC
- has PC/NFS, so it can access the same executables that gdb can,
- over the net in real time."
-
- In reality, this module talks to a debug monitor called 'ROMBUG', which
- We communicate with ROMBUG via a direct serial line, the network version
- of ROMBUG is not available yet.
