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