  Yes.  The flags parameter can be adjusted on the command line with -f, or by
  entering +!flags=_value_+ at the "Enter code:" prompt.  When the flags are set
  to 0, all characters from hex 20 to hex 7E are included.  The different bits

  There is a version field that can be incremented to produce a completely

  prompt.  The default version is 0, and values up to 2^32^-1 are accepted.  The
  version is encoded as part of the reminder.
