21 | /* This file was derived from remote-eb.c, which did a similar job, but for | |
22 | an AMD-29K running EBMON. That file was in turn derived from remote.c | |
23 | as mentioned in the following comment (left in for comic relief): | |
24 | ||
c5aa993b | 25 | "This is like remote.c but is for a different situation-- |
c906108c SS |
26 | having a PC running os9000 hook up with a unix machine with |
27 | a serial line, and running ctty com2 on the PC. os9000 has a debug | |
28 | monitor called ROMBUG running. Not to mention that the PC | |
29 | has PC/NFS, so it can access the same executables that gdb can, | |
30 | over the net in real time." | |
31 | ||
32 | In reality, this module talks to a debug monitor called 'ROMBUG', which | |
33 | We communicate with ROMBUG via a direct serial line, the network version | |
34 | of ROMBUG is not available yet. | |
