The options given to ``gdbserver`` (e.g. the + address on which to listen for connections) are taken from the ``$GDB_OPTIONS`` + environment variable. By default (if ``$GDB_OPTIONS`` is empty), it listens on + ``localhost:12345``. + It is possible to connect to it for example with + ``gdb -iex "target remote $addr"``, where ``$addr`` is the address + ``gdbserver`` listens on. + If the ``-gdb`` option is not used, ``$GDB_OPTIONS`` is ignored, + regardless of whether it is set or not. + * ``-d`` (debug) just increases the logging verbosity, showing for example the QMP commands and answers.
