板子启动后就会自动创建ttyS0之类的节点
inittab文件内容:
# /etc/inittab: init(8) configuration.

# The default runlevel.
id:5:initdefault:

# Boot-time system configuration/initialization script.
# This is run first except when booting in emergency (-b) mode.
si::sysinit:/etc/init.d/rcS

# What to do in single-user mode.
~~:S:wait:/sbin/sulogin

# /etc/init.d executes the S and K scripts upon change
# of runlevel.
#
# Runlevel 0 is halt.
# Runlevel 1 is single-user.
# Runlevels 2-5 are multi-user.
# Runlevel 6 is reboot.

# Normally not reached, but fallthrough in case of emergency.

如果将最后一行的console改为ttyS0就可以ctrl+c,但现在ttyS0别的要用
将console改为其他的不能ctrl+c;
内核源码也尝试改过............
busybox是1.15.1版本的,几个配置:job control选了,还有几个也选了的;目前还是很怀疑是配置问题,可配置没得改了,尝试了N次了;
求指点.....................................(新手,没币,见谅........)
