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