<br><font size=2 face="sans-serif">Hi everyone.</font>
<br>
<br>
<br><font size=2 face="sans-serif">I just wondering, if anyone outthere
can help me. I am currently kind of lost.</font>
<br>
<br><font size=2 face="sans-serif">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 size=2 face="sans-serif">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 size=2 face="sans-serif">All is working pretty perfect.</font>
<br>
<br><font size=2 face="sans-serif">So far so good. And now here comes my
problem. </font>
<br><font size=2 face="sans-serif">To add a better MMI in the future I
want to use the graphic card as an output.</font>
<br>
<br><font size=2 face="sans-serif">I added a graphic card to the
system. The kernel configuration includes framebuffer support for that
particular graphic card. </font>
<br><font size=2 face="sans-serif">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 size=2 face="sans-serif">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 size=2 face="sans-serif">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 size=2 face="sans-serif">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 size=2 face="sans-serif">So, how do I connect the serial line
/dev/ttySx to the standard input path of the virtual console.</font>
<br>
<br><font size=2 face="sans-serif">Any hint is welcomed. Any manuals to
read are also welcomed. </font>
<br>
<br><font size=2 face="sans-serif">Thanx</font>
