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.
