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

+// 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.
