Hi, Valids and others</div>
<div style="LINE-HEIGHT: 15pt">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.</div>
<div style="LINE-HEIGHT: 15pt">(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.</div>
<div style="LINE-HEIGHT: 15pt">Thanks all for good suggestions (not only this Ctrl-C but others like printf system call source location..).</div>
<div style="LINE-HEIGHT: 15pt">Best regards,</div>

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