// 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.
