Hi John, JimI had the same problem, but with an embedded Linux system. I found the solution on BusyBox, the write under FAQ
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. Your should run your shell on a normal tty such as tty1 or ttyS0 and everything will work perfectly. If you REALLY want your shell to run on /dev/console, then you can hack your kernel (if you are into that sortof thing) by changing drivers/char/tty_io.c to change the lines where it sets "noctty = 1;" to instead set it to "0". I recommend you instead run your shell on a real console...
There is also a lot of information about "job control turned off " in their mailing list.
I hope this helps. Alfred----- Original Message ----- From: "John Williams" <jwilliams@xxxxxxxxxxxxxx>

Hi Jim, jim bo wrote:I have the same problem not being able to stop apps using CRL-C and such key combinations.I've seen this too - will look into the cause.I'm having a problem right now mounting an NFS share on uClinux-2.4.32-uc0 on Microblaze. (followed Jason Wu tutorial for setting up on an ML401) When I try to mount the share (which can be NFS mounted by other machines on the network), it fails saying the server is not responding, still trying. The problem is it doesn't ever return to the shell prompt. I suppose it's possible the system has simply crashed and is not accepting input. But I've also had the problem when I first tried using ping from the uClinux shell... and there was no escaping it It's quite a bit of time to have to redownload the kernel image again.Are you running the "portmap" daemon on the uClinux board? Select it in the userspace menuconfig, under network apps.
