38 Frequency for default beep.
40 config FEATURE_BEEP_LENGTH_MS
46 Length in ms for default beep.
54 config FEATURE_CHAT_NOFAIL
55 bool "Enable NOFAIL expect strings"
59 When enabled expect strings which are started with a dash trigger
60 no-fail mode. That is when expectation is not met within timeout
61 the script is not terminated but sends next SEND string and waits
62 for next EXPECT string. This allows to compose far more flexible
65 config FEATURE_CHAT_TTY_HIFI
66 bool "Force STDIN to be a TTY"
70 Original chat always treats STDIN as a TTY device and sets for it
71 so-called raw mode. This option turns on such behaviour.
73 config FEATURE_CHAT_IMPLICIT_CR
74 bool "Enable implicit Carriage Return"
78 When enabled make chat to terminate all SEND strings with a "\r"
79 unless "\c" is met anywhere in the string.

86 Busybox chat require no options. To make it not fail when used
87 in place of original chat (which has a bunch of options) turn
90 config FEATURE_CHAT_SEND_ESCAPES
91 bool "Support weird SEND escapes"
95 Original chat uses some escape sequences in SEND arguments which
96 are not sent to device but rather performs special actions.
97 E.g. "\K" means to send a break sequence to device.
98 "\d" delays execution for a second, "\p" -- for a 1/100 of second.
99 Before turning this option on think twice: do you really need them?
101 config FEATURE_CHAT_VAR_ABORT_LEN
102 bool "Support variable-length ABORT conditions"
106 Original chat uses fixed 50-bytes length ABORT conditions. Say N here.

129 files and executes commands on behalf of the users in question.
130 This is a port of dcron from slackware. It uses files of the
131 format /var/spool/cron/crontabs/<username> files, for example:
132 $ cat /var/spool/cron/crontabs/root

231 This is obsolete and should NOT be used anymore.
232 Use linux >= 2.6 (optionally with hotplug) and mdev instead!
234 For legacy systems -- if there is no way around devfsd -- this
235 tells busybox to look for names like /dev/loop/0 instead of
236 /dev/loop0. If your /dev directory has normal names instead of
237 devfs names, you don't want this.

547 Preload the files listed on the command line into RAM cache so that
548 subsequent reads on these files will not block on disk I/O.
550 This applet just calls the readahead(2) system call on each file.
551 It is mainly useful in system startup scripts to preload files
552 or executables before they are used. When used at the right time
553 (in particular when a CPU bound process is running) it can
554 significantly speed up system startup.
556 As readahead(2) blocks until each file has been read, it is best to

657 The watchdog utility is used with hardware or software watchdog
658 device drivers. It opens the specified watchdog device special file

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