So, no init system or anything? Your terminal probably hasn't been set up. This is a surprisingly tricky bit of "magic" done with a special syscall which we're for the most part happy to let some linux distribution do for us.
One workaround for it, funny enough, could be ssh-ing into your device. A virtual terminal should be close enough.
I was sure that busybox had a utility for it, and their faq turns out to have that and a better explanation what it does:
Quote:
"Why do I keep getting "sh: can't access tty; job control turned off" errors? Why doesn't Control-C work within my shell?"
Job control will be turned off since your shell can not obtain a controlling terminal. This typically happens when you run your shell on /dev/console. The kernel will not provide a controlling terminal on the /dev/console device. You should run your shell on a normal tty such as tty1 or ttyS0 and everything will work.
Example: you booted into your machine with init=/bin/sh and got "sh: can't access tty" error because sh has its stdio opened to /dev/console. You want to reopen stdio to, say, /dev/tty1 and thus acquire a controlling tty.

LEARN ABOUT SUSE
showconsole
SHOWCONSOLE(8) The SuSE boot concept SHOWCONSOLE(8)NAME
Showconsole - determines the underlying tty of stdin
Setconsole - sets the underlying tty of /dev/console
SYNOPSIS
showconsole [-n]
setconsole /dev/tty<xy> < /dev/console
DESCRIPTION
showconsole determines the underlying character device of the current stdin. This can be used on /dev/console as current character device
to get the real character device back.
setconsole sets the underlying tty of the system console /dev/console. This requires that the standard input is identical with /dev/con-
sole and exactly one argument, a valid character device is given.
OPTIONS -n Return the major and minor device numbers instead of the device file name. This can be used to asked the kernel for the major and
minor device numbers of a not existing device file in /dev.
BUGS
showconsole needs a mounted /proc file system and tries to set the controlling tty to stdin if no controlling tty is found. After reading
/proc the status of the controlling tty is restored to avoid problems with getty processes.
FILES
/proc/<pid of showconsole>/stat
the stat file of the showconsole process.
/dev/console
the system console.
