+/* This structure describes the strings necessary to give small command
+ sequences to the monitor, and parse the response.
+
+ CMD is the actual command typed at the monitor. Usually this has
+ embedded sequences ala printf, which are substituted with the
+ arguments appropriate to that type of command. Ie: to examine a
+ register, we substitute the register name for the first arg. To
+ modify memory, we substitute the memory location and the new
+ contents for the first and second args, etc...
+
+ RESP_DELIM used to home in on the response string, and is used to
+ disambiguate the answer within the pile of text returned by the
+ monitor. This should be a unique string that immediately precedes
+ the answer. Ie: if your monitor prints out `PC: 00000001= ' in
+ response to asking for the PC, you should use `: ' as the
+ RESP_DELIM. RESP_DELIM may be NULL if the res- ponse is going to
+ be ignored, or has no particular leading text.
+
+ TERM is the string that the monitor outputs to indicate that it is
+ idle, and waiting for input. This is usually a prompt of some
+ sort. In the previous example, it would be `= '. It is important
+ that TERM really means that the monitor is idle, otherwise GDB may
+ try to type at it when it isn't ready for input. This is a problem
+ because many monitors cannot deal with type-ahead. TERM may be
+ NULL if the normal prompt is output.
+
+ TERM_CMD is used to quit out of the subcommand mode and get back to
+ the main prompt. TERM_CMD may be NULL if it isn't necessary. It
+ will also be ignored if TERM is NULL. */
