[BusyBox] How can i run my shell on normal tty?

Tue Jun 7 19:26:19 MDT 2005

Hi, guys. 
I keep getting "sh: can't access tty; job control turned off"? 
Why doesn't Control-C work within my shell? 
So, how can i run my shell on normal tty, such as tty1, ttyS0.

Do you have the good suggestion? Thank you!
