/* 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. */
