Hi all,
I've tried out the hush shell in busybox 1.6.1.
Seems to work fairly well with the patch last in
this mail.
The only(?) thing that doesn't work however, is
backspace... or to be more correct, it do backspace
in the commandline but it isn't displayed correctly.
If I have fancy editing enabling then the character
is moved to the RIGHT instead of LEFT when I backspace.
If I don't have fancy editing enabled, it prints out
some garbage (same all time) like:
~ # lsUP!) UP!)UP!) UP!)
(backspace pressed twice)
The only string I can find that looks like UP!) is:
[EMAIL PROTECTED] busybox-1.6.1]$ grep -r UP\! *
networking/ping.c: const char *dupmsg = " (DUP!)";
[EMAIL PROTECTED] busybox-1.6.1]$
So it seems like a weird pointer issue...
I use busybox 1.6.1, gcc 4.1.2 and kernel 2.6.19-uc1 on
a arm7tdmi'ish mcu.
Anyone encountered this behaviour?
