  54  ** USERCONFIG
  55  **
  56  ** Kernel boot-time configuration manipulation tool for FreeBSD.
  57  **
  58  ** Two modes of operation are supported : the default is the line-editor mode,
  59  ** the command "visual" invokes the fullscreen mode.
  60  **
  61  ** The line-editor mode is the old favorite from FreeBSD 2.0/20.05 &c., the
  62  ** fullscreen mode requires syscons or a minimal-ansi serial console.
  63  **/

  65 /**
  66  ** USERCONFIG, visual mode.
  67  **
  68  **   msmith@freebsd.org
  69  **
  70  ** Look for "EDIT THIS LIST" to add to the list of known devices
  71  **
  72  **
  73  ** There are a number of assumptions made in this code.
  74  **
  75  ** - That the console supports a minimal set of ANSI escape sequences
  76  **   (See the screen manipulation section for a summary)
  77  **   and has at least 24 rows.
  78  ** - That values less than or equal to zero for any of the device
  79  **   parameters indicate that the driver does not use the parameter.
  80  ** - That flags are _always_ editable.
  81  **
  82  ** Devices marked as disabled are imported as such.
  83  **
  84  ** For this tool to be useful, the list of devices below _MUST_ be updated
  85  ** when a new driver is brought into the kernel.  It is not possible to
  86  ** extract this information from the drivers in the kernel.
  87  **
  88  ** XXX - TODO:
  89  **
  90  ** - Display _what_ a device conflicts with.
  91  ** - Implement page up/down (as what?)
  92  ** - Wizard mode (no restrictions)
  93  ** - Find out how to put syscons back into low-intensity mode so that the
  94  **   !b escape is useful on the console.  (It seems to be that it actually
  95  **   gets low/high intensity backwards. That looks OK.)
  96  **
  97  ** - Only display headings with devices under them. (difficult)
