The bbconfig applet will print the config file with which
busybox was built.
+config CHAT
+ bool "chat"
+ default n
+ help
+ Simple chat utility.
+
+config FEATURE_CHAT_NOFAIL
+ bool "Enable NOFAIL expect strings"
+ default y
+ help
+ When enabled expect strings which are started with a dash trigger
+ no-fail mode. That is when expectation is not met within timeout
+ the script is not terminated but sends next SEND string and waits
+ for next EXPECT string. This allows to compose far more flexible
+ scripts.
+
+config FEATURE_CHAT_TTY_HIFI
+ bool "Force STDIN to be a TTY"
+ default n
+ help
+ Original chat always treats STDIN as a TTY device and sets for it
+ so-called raw mode. This option turns on such behaviour.
+
+config FEATURE_CHAT_IMPLICIT_CR
+ bool "Enable implicit Carriage Return"
+ default y
+ help
+ When enabled make chat to terminate all SEND strings with a "\r"
+ unless "\c" is met anywhere in the string.
+
+config FEATURE_CHAT_SWALLOW_OPTS
+ bool "Swallow options"
+ default n
+ help
+ Busybox chat require no options. To make it not fail when used
+ in place of original chat (which has a bunch of options) turn
+ this on.
+
+config FEATURE_CHAT_SEND_ESCAPES
+ bool "Support weird SEND escapes"
+ default n
+ help
+ Original chat uses some escape sequences in SEND arguments which
+ are not sent to device but rather performs special actions.
+ E.g. "\K" means to send a break sequence to device.
+ "\d" delays execution for a second, "\p" -- for a 1/100 of second.
+ Before turning this option on think twice: do you really need them?
+
+config FEATURE_CHAT_VAR_ABORT_LEN
+ bool "Support variable-length ABORT conditions"
+ default n
+ help
+ Original chat uses fixed 50-bytes length ABORT conditions. Say N here.
+
+config FEATURE_CHAT_CLR_ABORT
+ bool "Support revoking of ABORT conditions"
+ default n
+ help
+ Support CLR_ABORT directive.
+
config CHRT
bool "chrt"
default n
