55 ** Kernel boot-time configuration manipulation tool for FreeBSD.
57 ** Two modes of operation are supported : the default is the line-editor mode,
58 ** the command "visual" invokes the fullscreen mode.
60 ** The line-editor mode is the old favorite from FreeBSD 2.0/20.05 &c., the
61 ** fullscreen mode requires syscons or a minimal-ansi serial console.
65 ** USERCONFIG, visual mode.
69 ** Look for "EDIT THIS LIST" to add to the list of known devices
72 ** There are a number of assumptions made in this code.
74 ** - That the console supports a minimal set of ANSI escape sequences
75 ** (See the screen manipulation section for a summary)
76 ** and has at least 24 rows.
77 ** - That values less than or equal to zero for any of the device
78 ** parameters indicate that the driver does not use the parameter.
79 ** - That flags are _always_ editable.
81 ** Devices marked as disabled are imported as such.
83 ** For this tool to be useful, the list of devices below _MUST_ be updated
84 ** when a new driver is brought into the kernel. It is not possible to
85 ** extract this information from the drivers in the kernel.
89 ** - Display _what_ a device conflicts with.
90 ** - Implement page up/down (as what?)
91 ** - Wizard mode (no restrictions)
92 ** - Find out how to put syscons back into low-intensity mode so that the
93 ** !b escape is useful on the console. (It seems to be that it actually
94 ** gets low/high intensity backwards. That looks OK.)
96 ** - Only display headings with devices under them. (difficult)
