how can i get backspace working ?

[fabien]

Hi,
I've compiled busybox with allnoconfig and apply myself a custom configuration.
The system works but the backspace doesn't work properly i get : ^h
I've configured to use ash, i've also modified the inittab to work
with my CPM driver /dev/ttyCPM0.
My kernel is a 2.6.23 and busybox 1.8.1 compiled with µClibc.
If someone could give me the way or a clue to solve this problem.

My busybox config is like this :
CONFIG_HAVE_DOT_CONFIG=y
CONFIG_FEATURE_SYSLOG=y
CONFIG_STATIC=y
CONFIG_NO_DEBUG_LIB=y
CONFIG_INSTALL_APPLET_SYMLINKS=y
CONFIG_BASENAME=y

CONFIG_ASH_BUILTIN_ECHO=y
CONFIG_ASH_BUILTIN_TEST=y
CONFIG_ASH_MAIL=y
CONFIG_ASH_OPTIMIZE_FOR_SIZE=y
CONFIG_BUSYBOX_EXEC_PATH="/bin/busybox"

my etc/inittab :
::sysinit:/etc/init.d/rcS
ttyCPM0::askfirst:-/bin/sh
::restart:/sbin/init
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
::shutdown:/sbin/swapoff -a

In rcS there is just a mount proc command.

Best regards
