    sys/kern             tty_cons.c 
  Log:
  Add a new cn_flags fields to struct consdev, the low-level console
  definition structure.  Define one flag, CN_FLAG_NODEBUG, which
  indicates the console driver cannot be used in the context of the
  debugger.  This may be used, for example, if the console device
  interacts with kernel services that cannot be used from the
  debugger context, such as the network stack.  These drivers are
  skipped over for calls to cn_checkc() and cn_putc(), and the
  calling function simply moves on to the next available console.
