+/* 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.
