33 // OBSOLETE * REMOTE COMMUNICATION PROTOCOL BETWEEN GDB960 AND THE NINDY ROM MONITOR.
36 // OBSOLETE * MODES OF OPERATION
37 // OBSOLETE * ----- -- ---------
39 // OBSOLETE * As far as NINDY is concerned, GDB is always in one of two modes: command
40 // OBSOLETE * mode or passthrough mode.
42 // OBSOLETE * In command mode (the default) pre-defined packets containing requests
43 // OBSOLETE * are sent by GDB to NINDY. NINDY never talks except in reponse to a request.
45 // OBSOLETE * Once the the user program is started, GDB enters passthrough mode, to give
46 // OBSOLETE * the user program access to the terminal. GDB remains in this mode until
47 // OBSOLETE * NINDY indicates that the program has stopped.
50 // OBSOLETE * PASSTHROUGH MODE
51 // OBSOLETE * ----------- ----
53 // OBSOLETE * GDB writes all input received from the keyboard directly to NINDY, and writes
54 // OBSOLETE * all characters received from NINDY directly to the monitor.
56 // OBSOLETE * Keyboard input is neither buffered nor echoed to the monitor.
58 // OBSOLETE * GDB remains in passthrough mode until NINDY sends a single ^P character,
59 // OBSOLETE * to indicate that the user process has stopped.
62 // OBSOLETE * GDB assumes NINDY performs a 'flushreg' when the user program stops.
65 // OBSOLETE * COMMAND MODE
66 // OBSOLETE * ------- ----
68 // OBSOLETE * All info (except for message ack and nak) is transferred between gdb
69 // OBSOLETE * and the remote processor in messages of the following format:
71 // OBSOLETE * <info>#<checksum>
74 // OBSOLETE * # is a literal character
76 // OBSOLETE * <info> ASCII information; all numeric information is in the
77 // OBSOLETE * form of hex digits ('0'-'9' and lowercase 'a'-'f').
79 // OBSOLETE * <checksum>
80 // OBSOLETE * is a pair of ASCII hex digits representing an 8-bit
81 // OBSOLETE * checksum formed by adding together each of the
82 // OBSOLETE * characters in <info>.
84 // OBSOLETE * The receiver of a message always sends a single character to the sender
85 // OBSOLETE * to indicate that the checksum was good ('+') or bad ('-'); the sender
86 // OBSOLETE * re-transmits the entire message over until a '+' is received.
88 // OBSOLETE * In response to a command NINDY always sends back either data or
89 // OBSOLETE * a result code of the form "Xnn", where "nn" are hex digits and "X00"
90 // OBSOLETE * means no errors. (Exceptions: the "s" and "c" commands don't respond.)
92 // OBSOLETE * SEE THE HEADER OF THE FILE "gdb.c" IN THE NINDY MONITOR SOURCE CODE FOR A
93 // OBSOLETE * FULL DESCRIPTION OF LEGAL COMMANDS.
95 // OBSOLETE * SEE THE FILE "stop.h" IN THE NINDY MONITOR SOURCE CODE FOR A LIST
96 // OBSOLETE * OF STOP CODES.
