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.
