login on console=tty with serial input<BR></FONT><BR></DIV>
<DIV></DIV><BR><FONT face=sans-serif size=2>Hi everyone.</FONT>
<BR><BR><BR><FONT face=sans-serif size=2>I just wondering, if anyone outthere
can help me. I am currently kind of lost.</FONT> <BR><BR><FONT face=sans-serif
size=2>I have an embedded powerpc based system running with kernel 2.6.20.
The system has only two serial lines and no PS/2 or USB support.
Therefore I control the system via a serial console ( passing the commandline
arg: console=ttyS0,57600) and a terminal.</FONT> <BR><FONT face=sans-serif
size=2>A getty program is running on /dev/console, which gives me a login:
prompt, so I can login via the serial line ttyS0.</FONT> <BR><FONT
face=sans-serif size=2>All is working pretty perfect.</FONT> <BR><BR><FONT
face=sans-serif size=2>So far so good. And now here comes my problem.
</FONT><BR><FONT face=sans-serif size=2>To add a better MMI in the future I
want to use the graphic card as an output.</FONT> <BR><BR><FONT
face=sans-serif size=2>I added a graphic card to the system. The kernel
configuration includes framebuffer support for that particular graphic card.
</FONT><BR><FONT face=sans-serif size=2>After booting the kernel, I can see a
/dev/fb0 device and testing with 'echo "hello" > /dev/fb0', the message
"hello" is displayed on the screen. </FONT><BR><FONT face=sans-serif
size=2>Also if I add the commandline arg: console=tty console=ttyS0,57600 , I
get all kernel messages displayed, not only on the serial line, but also on
the screen via the framebuffer.</FONT> <BR><BR><FONT face=sans-serif size=2>So
basically, what I want is graphical output (dev/fb0) with serial input
(/dev/ttyS0). The user sees a login prompt on the screen and can enter
characters by a terminal program connected to the serial line.</FONT>
<BR><FONT face=sans-serif size=2>Right to that point I always used the serial
console for user interaction. By adding only the commandline argument
console=tty, I get a nice login prompt on the graphic screen. BUT I have no
input via the serial line???</FONT> <BR><BR><FONT face=sans-serif size=2>So,
how do I connect the serial line /dev/ttySx to the standard input path
of the virtual console.</FONT> <BR><BR><FONT face=sans-serif size=2>Any hint
is welcomed. Any manuals to read are also welcomed. </FONT><BR><BR><FONT
