Hi Harald
Did you find a solution for your problem?
I have almost a similar problem.
On a MPC885 board I have one serial line, an Ethernet port and a QVGA display
with a /dev/fb.
As GUI library, I started to evaluate Nano-X, FLTK and wxWitgets. But there is
the problem that I don't have keyboard input whether form the serial line nor
form a remote shell (Ethernet).
As far I understand the matter the problem is that the console that is running
on the frame buffer needs as input a keyboard device and not a serial line.
Unfortunately I found till now no solution to redirect the serial line to a
keyboard device.

Subject: login on console=tty with serial input
Hi everyone.
I just wondering, if anyone outthere can help me. I am currently kind
of lost.
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.
A getty program is running on /dev/console, which gives me a login:
prompt, so I can login via the serial line ttyS0.
All is working pretty perfect.
So far so good. And now here comes my problem.
To add a better MMI in the future I want to use the graphic card as an
output.
I added a graphic card to the system. The kernel configuration
includes framebuffer support for that particular graphic card.
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.
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.
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.
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???
So, how do I connect the serial line /dev/ttySx to the standard input
path of the virtual console.
Any hint is welcomed. Any manuals to read are also welcomed.
Thanx
Harald Brüggemann
