25 config FEATURE_COMPRESS_BBCONFIG
26 bool "Compress bbconfig data"
30 Store bbconfig data in compressed form, uncompress them on-the-fly
33 If you have a really tiny busybox with few applets enabled (and
34 bunzip2 isn't one of them), the overhead of the decompressor might
35 be noticeable. Also, if you run executables directly from ROM
36 and have very little memory, this might not be a win. Otherwise,
37 you probably want this.

52 Frequency for default beep.
54 config FEATURE_BEEP_LENGTH_MS
60 Length in ms for default beep.
68 config FEATURE_CHAT_NOFAIL
69 bool "Enable NOFAIL expect strings"
73 When enabled expect strings which are started with a dash trigger
74 no-fail mode. That is when expectation is not met within timeout
75 the script is not terminated but sends next SEND string and waits
76 for next EXPECT string. This allows to compose far more flexible
79 config FEATURE_CHAT_TTY_HIFI
80 bool "Force STDIN to be a TTY"
84 Original chat always treats STDIN as a TTY device and sets for it
85 so-called raw mode. This option turns on such behaviour.
87 config FEATURE_CHAT_IMPLICIT_CR
88 bool "Enable implicit Carriage Return"
92 When enabled make chat to terminate all SEND strings with a "\r"
93 unless "\c" is met anywhere in the string.

101 in place of original chat (which has a bunch of options) turn
104 config FEATURE_CHAT_SEND_ESCAPES
105 bool "Support weird SEND escapes"
109 Original chat uses some escape sequences in SEND arguments which
110 are not sent to device but rather performs special actions.
111 E.g. "\K" means to send a break sequence to device.
112 "\d" delays execution for a second, "\p" -- for a 1/100 of second.
113 Before turning this option on think twice: do you really need them?
115 config FEATURE_CHAT_VAR_ABORT_LEN
116 bool "Support variable-length ABORT conditions"
120 Original chat uses fixed 50-bytes length ABORT conditions. Say N here.

127 Support CLR_ABORT directive.

141 Crond is a background daemon that parses individual crontab
142 files and executes commands on behalf of the users in question.
143 This is a port of dcron from slackware. It uses files of the
144 format /var/spool/cron/crontabs/<username> files, for example:
145 $ cat /var/spool/cron/crontabs/root

245 Use linux >= 2.6 (optionally with hotplug) and mdev instead!
247 For legacy systems -- if there is no way around devfsd -- this
248 tells busybox to look for names like /dev/loop/0 instead of
249 /dev/loop0. If your /dev directory has normal names instead of
250 devfs names, you don't want this.

561 subsequent reads on these files will not block on disk I/O.
563 This applet just calls the readahead(2) system call on each file.
564 It is mainly useful in system startup scripts to preload files
565 or executables before they are used. When used at the right time
566 (in particular when a CPU bound process is running) it can
567 significantly speed up system startup.

674 certain amount of time, the watchdog device assumes the system has
675 hung, and will cause the hardware to reboot.
