Ah, of coursee Ctrl-C works on the console and LCD shells. I set the Job-Constrol option in the busybox shell options. ________________________________ From : "Chan Kim" <c...@etri.re.kr> Sent : 2014-04-09 10:03:10 ( +09:00 ) To : valdis.kletni...@vt.edu <valdis.kletni...@vt.edu> Cc : kernelnewbies@kernelnewbies.org <kernelnewbies@kernelnewbies.org> Subject : RE: Ctrl-C doesn't work in the shell
Hi, Valids and others I saw the email replies only yesterday afternoon. Reading those and other internet posts, reallized my shell on the LCD is working as a console. (When I type tty, it responds with 'console'). So I set the boot argument 'console' back to ttyS (serial port) and removed the etc/inittab so that default inittab will take effect. Default inittab starts shell on tty2, tty3 and tty4. And I ran it and vola! the console is in the UART terminal and I could switch to different shell windows by pressing Alt-F2, Alt-F3 and Alt-F4. I now have console on the UART terminal and 3 shells on the LCD which I can switch between. Thanks all for good suggestions (not only this Ctrl-C but others like printf system call source location..). Best regards, Chan ________________________________ From : "valdis.kletni...@vt.edu" <valdis.kletni...@vt.edu> Sent : 2014-04-01 23:13:49 ( +09:00 ) To : Chan Kim <c...@etri.re.kr> Cc : kernelnewbies@kernelnewbies.org <kernelnewbies@kernelnewbies.org> Subject : Re: Ctrl-C doesn't work in the shell On Tue, 01 Apr 2014 05:57:05 -0000, Chan Kim said: > When I'm on a sheel on LCD using USB keyboard, all works fine (except another > important problem..) but Ctrl-C key doesn't work. > When I press ctrl-C, '^C' is displayed on the screen (prompt line), but > doesn't have the effect of killing the job.

This often happens if you've managed to launch a shell that doesn't set itself up as "interactive" and/or acquire a control terminal. Quick test - if you do a 'ps', does the shell process show up with a ? or with a tty? If it shows ?, it hasn't gotten a control terminal. Your shell may have a '-i' flag to make it interactive and/or a '-l' to make it be a login shell, those flags may be an easy way to fix the problem.
