- *
- * 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.
