+ depends on BUSYBOX_CONFIG_CHAT
+ default n
+ 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 BUSYBOX_CONFIG_FEATURE_CHAT_TTY_HIFI
+ bool "Force STDIN to be a TTY"
+ depends on BUSYBOX_CONFIG_CHAT
+ default n

+config BUSYBOX_CONFIG_FEATURE_CHAT_SEND_ESCAPES
+ bool "Support weird SEND escapes"
+ depends on BUSYBOX_CONFIG_CHAT
+ 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.

This tells busybox to look for names like /dev/loop/0 instead of
/dev/loop0. If your /dev directory has normal names instead of
devfs names, you don't want this.
