set interactive-mode (on|off|auto)
show interactive-mode
Control whether GDB runs in interactive mode (on) or not (off).
When in interactive mode, GDB waits for the user to answer all
queries. Otherwise, GDB does not wait and assumes the default
answer. When set to auto (the default), GDB determines which
mode to use based on the stdin settings.
