-/* 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 an esoteric situation--
-   having an a29k board in a PC hooked up to a unix machine with
-   a serial line, and running ctty com1 on the PC, through which
-   the unix machine can run ebmon.  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 'STDEBUG', which
-   runs in a phone switch.  We communicate with STDEBUG via either a direct
-   serial line, or a TCP (or possibly TELNET) stream to a terminal multiplexor,
-   which in turn talks to the phone switch. */
