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