any sequence of digits.
Notes:
• All output sequences end in a single line containing a period.
• The token is from the corresponding request. If an execution command is interrupted
by the ‘-exec-interrupt’ command, the token associated with the ‘*stopped’ message
is the one of the original execution command, not the one of the interrupt command.
• status-async-output contains on-going status information about the progress of a slow
operation. It can be discarded. All status output is prefixed by ‘+’.
• exec-async-output contains asynchronous state change on the target (stopped, started,
disappeared). All async output is prefixed by ‘*’.
• notify-async-output contains supplementary information that the client should handle
(e.g., a new breakpoint information). All notify output is prefixed by ‘=’.
• console-stream-output is output that should be displayed as is in the console. It is the
textual response to a CLI command. All the console output is prefixed by ‘~’.
