Description Explorer09 2012-09-04 15:06:47 UTC 
To reproduce this bug:

1. Run busybox ash shell
2. Type 'read -s'
3. Press Ctrl+C to abort the reading.

Actual result:

From now, every character I type will be invisible. Even newlines are invisible too.

For example, when I type multiple enters and then 'ls' then enter, my shell screen looks something like this:
---------------------------------------------
/ $ / $ / $ / $ / $ / $ / $ / $ bin    dev   initrd.img  lost+found  opt   run	    srv  usr
boot   etc   lib	 media	     proc  sbin     sys  var
cdrom  home  lib64	 mnt	     root  selinux  tmp  vmlinuz
---------------------------------------------

Expected result:

The input characters I type should be visible like before. Like this:
---------------------------------------------
/ $ 
/ $ 
/ $ 
/ $ ls
bin    dev   initrd.img  lost+found  opt   run	    srv  usr
boot   etc   lib	 media	     proc  sbin     sys  var
cdrom  home  lib64	 mnt	     root  selinux  tmp  vmlinuz
---------------------------------------------
