control+c signal is not working

I am using linux 2.6.32.13-Cavium-Octeon with MIPS architecture. On terminal when i press ctrl+c to terminate process; nothing happen. How can I trace this in my kernel to handle with it issue?
'stty -a' output is:
speed 115200 baud; rows 0; columns 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

Is there any issue with tty? Because when i "make menuconfig" there is no option for "enable tty"
and command "bind -v" is also not working.

Thanks

Go to another TTY, use psgrep to get the PID of the proccess and then:
Or install Htop, and use it to kill the process.
