/* 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.
